FRITZ SCHIDER-AN ATLAS OF ANATOMY FOR ARTISTS PDF

Note: The female skeleton is clearly differentiated from the male by the small face and skull, the narrow, short thorax, and particularly the more rounded pelvis compare the drawings. The various joints are classified according to the shape of the articular surfaces. Ball and Socket Joints. The ball and socket joint consists of a spherical head which fits into a cavity, the acetabulum, and which allows motion in all directions. Flexion, extension, adduction, and circumduction are possible in this type of joint.

Note: The female skeleton is clearly differentiated from the male by the small face and skull, the narrow, short thorax, and particularly the more rounded pelvis compare the drawings. The various joints are classified according to the shape of the articular surfaces. Ball and Socket Joints. The ball and socket joint consists of a spherical head which fits into a cavity, the acetabulum, and which allows motion in all directions.

Flexion, extension, adduction, and circumduction are possible in this type of joint. Hinge Joints. The joints of the fingers, the inter-phalangeal joints, are shown as examples of this type.

In a hinge joint, one bone has a transverse convex cylindrical surface and the other bone shows the reciprocal contour. Only flexion and extension are possible in such a joint. The elbow joint is shown as an example of this type of joint. Three or more articular surfaces with various shapes are involved: the joint between the ulna and the humerus forms a hinge joint while the joint between the radius and the humerus is of the ball and socket type.

In addition, there is a special joint between the ulna and radius. In this combined joint, pronation and supination, flexion and extension are possible. Pronation refers to the motion of rotating the palm of the hand inwards towards the body; the pronated position of the forearm and hand is the position assumed after maximum inward rotation—the palm then faces outwards.

Supination refers to the opposite motion, i. The joints between the individual wrist carpal and ankle tarsal bones and between the carpal and metacarpal, tarsal and metatarsal bones are examples of this type.

Plate 6, Fig. In Fig. The two occipital condyles with joint surfaces which articulate with concave facets on the first cervical vertebra. The occipital protuberance to which the ligamentum nuchae "ligament of the neck" isattached. The mastoid processes, the styloid processes, and the external occipital crest which serve for the origin or insertion of muscles. The foramen magnum is the connection between the cranial cavity and the vertebral spinal canal.

In this drawing, significant features as far as external appearance is concerned are:. The two frontal prominences — rounded protuberances more definitely marked in children and women than in men;. The two superciliary arches — slender ridges above the orbits more distinctly marked in men than in women or children;.

The temporal lines — characteristically individual lines which form the lateral margins of the forehead;. The zygomatic bones with their very prominent zygomatic processes forming the anterior portions of the zygomatic arches;.

Plate 7, Figs. Sutural lines have not formed as yet. Instead, membrane-covered spaces are present between bones concerned. The frontal bone consists of two portions, unfused as yet. As a result of the teeth falling out, the mandible is thinned, the angle of the mandible obtuse, the mandible extends beyond the maxilla, and the chin protrudes.

These plates include the bones of the trunk consisting of the spinal column and the thoracic cage. The spinal column of the adult consists of 24 distinct true vertebrae, the sacrum, and the coccyx. The 24 true vertebrae are made up of 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae.

The sacrum consists of 5 fused false vertebrae; the coccyx, 4 fused vertebrae. The thoracic cage includes the sternum and 12 pairs of ribs.

The upper 7 ribs true ribs are directly connected to the sternum by their costal cartilages; of the lower 5 ribs false ribs , the eighth, ninth, and tenth are attached by their costal cartilages to the costal cartilage of the seventh rib, forming thereby the inferior thoracic margin, clearly indicated in the living. The eleventh and twelfth ribs lie within the posterior abdominal wall with their anterior ends unattached "floating" ribs.

The first cervical vertebra atlas ; note the concave articular facets into which the occipital condyles fit. The seventh cervical vertebra; note a bifurcated spinous process and perforated transverse process. The first thoracic vertebra; note the articular facets for the ribs.

The nodding motion between the head and first cervical vertebra and the rotatory motion between first and second cervical vertebrae are not shown.

Only the movements of the spinal column from the third cervical vertebra to the sacrum are illustrated: forward and backward flexion, lateral right and left flexion, and rotation about the longitudinal axis.

Forward and backward flexion are performed predominantly in the cervical and lumbar portions. For this purpose, the thoracic portion of the spine with the thorax may be considered as fixed. Also, lateral flexion occurs in the main in the cervical and lumbar portions.

Rotation about the longitudinal axis occurs, on the other hand, predominantly in the thoracic portion of the spine and particularly in its lower part. Rotation from the eighth to the twelfth thoracic vertebrae may be as much as 28 degrees.

Total amount of rotation from the third cervical vertebrae to the sacrum is about 47 degrees. Subdivisions B, C, D, E together make up the upper extremity proper or the "free" portion of the upper extremity. Plate 14 , Fig. Note: This position of the forearm is midway between supination and pronation. For purposes of strict anatomical description, the "anterior view" of the forearm is the anterior aspect of the supinated forearm with palm facing directly forward.

The outer aspect of the forearm and hand in this position is also called the lateral or radial side. The inner aspect is also called the medial or ulnar side. Note the S-shaped clavicle, the apex of the shoulder formed by the acromion process of the scapula, the coracoid process of the scapula, the humerus with its characteristic joint surfaces, the bones of the forearm articulating with the humerus, and finally, below the forearm, the bones of the wrist, palm, and fingers carpal bones, metacarpal bones and phalanges.

Note the foreshortened clavicle and acromion process, the medial epicondyle of the humerus, the crossed bones of the forearm, and the lateral aspect of the wrist and hand. Plate 15 , Fig. Note the axillary border of the scapula, the foreshortened clavicle, the clearly demonstrated head of the humerus and lateral epicondyle of the humerus, the adjacent S-shaped bones of the forearm, and the side view of the wrist and hand.

Note that the scapula is seen in its entire extent and that both epicondyles of the humerus are well demonstrated. Extensor muscles are attached to the lateral epicondyle; flexor muscles to the medial epicondyle.

The ulna is well seen, especially its upper end or olecranon, and its lower end, the styloid process and the head which form a prominence just above the wrist. The two innominate bones Each innominate bone is made up of three bones distinct in development but fused in the adult—the pubis, ischium, and ilium. The innominate bones, the sacrum, and coccyx, together, form the pelvis, sometimes called the pelvic girdle. Plate 16 , Fig. Note the half-pelvis, the innominate bone with well-marked anterior superior and inferior spines, the femur with its well-developed ends, the patella, the two leg bones, and the bones of the foot viewed from above and in front.

The bones of the foot consist of the tarsal bones, the metatarsal bones, and the bones of the toes phalanges. Note the half-pelvis, the innominate bones with well-marked posterior superior and inferior spines, the ischium with its tuberosity and spine, the femur with the two tro-chanters at its upper end and the two condyles at its lower end, the tibia articulating with the femur at the knee joint, the fibula, and the bones of the foot. Plate 17 , Fig.

Note the foreshortened pelvis, the medial condyle of the femur, the prominent tibial tuberosity at the upper end of the tibial crest, and the medial aspect of the bones of the foot. Note the half-pelvis with prominent iliac crest, the femur and patella, the tibia with its tuberosity, the fibula with the fibular head at its upper end, and the lateral aspect of the bones of the foot. Plate 18 shows the ligamentous capsule of the hip joint and the ligaments of the elbow joint.

Plate 19 shows the knee joint with and without its capsule. The capsule is re- enforced by accessory ligaments, not only on the outside of the joint but also within the joint as cruciate ligaments. Note the position of the two fat pads below the patella. These fat pads determine to a considerable extent the external appearance of the knee. A typical muscle may be said to consist of a central, red, fleshy or "muscular" portion the belly which changes its length and a tendon which does not alter its length but is stretched when the muscular portion is shortened.

Plate 20, Fig. In general, the "origin" of a muscle is the uppermost muscle attachment or the muscle attachment nearest the midline of the body, while the opposite muscle attachment is called the "insertion. Tendons appear in several forms:. As terminal tendons, attached at the end of the muscle, e. As interstitial tendons, inserted in the substance of the muscle belly, e.

As sheets, bands, or strands which frequently extend from the origin or insertion deep into the muscle substance, e. As aponeuroses—the term used for broad extensive tendon sheets, e. As tendinous sheets or bands which cover a portion of the muscle belly, e. Muscles with two, three, or more heads which arise at different sites and fuse into one belly, e. Muscles with a single belly which divides into several slips which insert independently, e. Broad muscles which, besides contracting, serve also to cover or protect body cavities, e.

Note: The term fascia is applied to a membranous connective tissue sheet which surrounds a muscle or muscle group.
