Medial in the center of the pelvis, where the two pubis bones meet. 6. Which adaptation would have would have taken place in the pubic symphysis of the female skeleton during the latter stages of pregnancy in preparation for the birthing process? The hormone relaxin increases the flexibility of the pubic symphysis to ease the delivery of the baby. 7.
* The cartilage of the pubic bone. ( Pelvic area) F. Which adaptation would have taken place in the pubic symphysis of female skeleton during the later stages of her pregnancy in preparation for the birthing process? * The relaxin hormone helps increases the laxity of the pubis symphysis allowing the mother pubic to become more flexible and stretch to allow passage of the baby during birth. G. What clues could Stefan have used to identify the gender of the pelvis? * The male pelvis is much more narrow and heavier than the female pelvis which is

2. Which type of bone provides a large, flat surface area for muscle attachment? The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, os coxæ (hip bone), sternum, and ribs. 3. Describe the location, composition, and function of the epiphyseal plate?
He can also look at the deep olecranon fossa on the posterior side (where the olecranon process of the ulna fits in when the elbow is straightened). D. The reason Stefan thinks that an enlarged right deltoid tuberosity might indicate right-handedness is because the deltoid tuberosity is the sight of attachment of the tendons of the deltoid muscle (a large and powerful muscle of the shoulder joint). When this hand is used more often it tends to distinctively shape the surface anatomy of the shoulder and humerus. E. The location of the pubic symphysis that Stefan refers to in the story is a joint where the hip bones unite anteriorly. They

Movement is in a single plane as that of a hinged door. Identify the trochelea and the trochlear notch. Ball and Socket: This is a joint where the ball-shapped surface of one rounded bone fits into a cup-like depression of another bone. Identify the acetabulum and the femur head. From the Synovial Joint page, click Specific Synovial Joints.
The parietal bone is elongated and compressed, as opposed to the rounded human parietal bone. 3. Compare the shape and position of the occipital bones in the human and chimpanzee skulls. How does the difference in the position of the foramen magnum, a large opening in the base of the skull for the spinal cord, correlate with the posture and stance of the two organisms? The occipital in humans is rounded; in the chimpanzee, it has a prominent ridge for attachment of neck muscles.
