1. Which clue would tell Stefan which scapular surface was anterior and which was posterior? What is the name of the shallow, oval socket of the scapula that Stefan placed next to the humerus? The posterior side of the scapula has the spine, the anterior is smooth and has the subscapular fossa. The oval socket is called the Glenoid cavity and is the scapular rotation surface for the humerus.
* 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
174 – a) shaft of the bone, b) end of the bone, c) between the shaft and end of the bone 7. Describe the location, composition, and function of the epiphyseal plate, articular cartilage, and periosteum. Ans: pg. 174 – epiphyseal plate: located in the metaphysis, composed of hyaline cartilage, is the growth plate; articular cartilage: covers the part of the epiphysis where the bone forms an articulation with another bone, composed of hyaline cartilage, reduces fiction and absorbs shock at freely movable joints; periosteum: surrounds the bone surface wherever it is not covered by articular cartilage, is a sheath of dense irregular connective tissue containing osteoblasts, functions to protect the bone, assists in fracture repair, nourishes bone tissue, and serve as an attachment point for ligaments and tendons 8. Why is osseous tissue considered a connective tissue?
Which portion of the parietal peritoneum is attached to the lesser curvature of the stomach? 209. Which portion of the parietal peritoneum is attached to the greater curvature of the stomach? 210. The lesser omentum attaches the stomach to _________.
B. The bone that Stefan is referring to as the “collarbone” is the clavicle (the S-shaped long, slender bone that lies horizontally across the anterior part of the thorax superior to the first rib). C. The surface marking that Stefan could use to distinguish the right humerus from the left humerus is if he holds the bone so that the capitulum and the trochlea face him (anterior) and then look at the head of the humerus (rounded head is superior (up) and pointing medially(towards the body’s midline)). If the head is facing left it is the left humerus, and if the head is facing right, it is the right humerus. 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).
It also allows for bones to heal and creates a stronger bone. It also restructures the bone extracellular matrix, where the shape of a bone is changed slightly, so that the bone can support more stress, be stronger, and/or thicker. 7. Which marking of the skull articulates with the first cervical vertebra? The occipital condyles is the oval process with convex surface on either side of the foramen magnum and it articulates with the first cervical vertebra (atlas) which allows a person to nod their head “yes”.
Gomphosis: A joint that binds the teeth to bony sockets in the maxillary bone and mandible. b. Why are sutures and gomphoses classified as synarthroses? These sutures are fibrous joints that are immovable. c. Syndesmoses are functionally a bit different.
When a surgeon amputates a leg, he or she makes a _Transverse_ cut through the bone. 7. The left eye is __Medial_ to the left ear. 8. In anatomical position, the thumb is _Lateral_ to the little finger.
-The structures that might be missing from an excavated skull would be the inferior nasal conchae, the vomer, and the perpendicular plate D. How would Hassan and his team be able to tell the ages of the skeletal remains of the women and the baby? -Hassan can tell the ages of the baby and the women by using the four kinds of sutures in the skull. They are: coronal suture, sagittal suture, lamboid suture, and squamous sutures, E. What features of the vertebral column would the larger skeleton in the sarcophagus show to indicate that it was female. -The feature about the spinal column that would indicate the skeleton was female is was the size of the vertebrae itself. Females tend to have smaller vertebrae the miles.
