The ligaments between the femur and pelvis. 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. B. 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. Female Pelvis C. Combination Type of Joint. of the forearm and hand is the position assumed after maximum inward rotationthe palm then faces outwards.

Supination refers to the opposite motion, i.e. rotating the palm outwards away from the body; the supinated position is the position assumed after maximum outward rotationthe palm faces forward and slightly outwards.) D. Immobile Type of Joint. . 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.

The two mandibular fossae in which the articular processes of the mandible move. C. The occipital protuberance to which the ligamentum nuchae (ligament of the neck) isattached. D. The mastoid processes, the styloid processes, and the external occipital crest which serve for the origin or insertion of muscles. E.

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: A. The two frontal prominences rounded protuberances more definitely marked in children and women than in men; B. The two superciliary arches slender ridges above the orbits more distinctly marked in men than in women or children; C. The glabella a small, flat surface between the superciliary arches; D.

The temporal lines characteristically individual lines which form the lateral margins of the forehead; E. The nasal bones; F. The zygomatic bones with their very prominent zygomatic processes forming the anterior portions of the zygomatic arches; G. The chin formed by the central part of the mandible. show the skull of the newborn, viewed from above and from the left side. 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. demonstrates the senile skull. 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. demonstrate the contours of three different skulls with their sutures.
