BioS255 comprehensive exam
1. Function of nervous system: -Control of body's internal environment to
maintain 'homeostasis'
-Programming of spinal cord reflexes
-Memory and learning
-Voluntary control of movement
2. Positive & negative feedback: A positive feedback loop causes a self-
amplifying cycle where a physiological change leads to even greater change in
the same direction.
A negative feedback loop is a process in which the body senses a change, and
activates mechanisms to reverse that change.
3. The name of the joint in the ankle: talocrural joint
4. characteristics of epithelial tissue: cellularity, polarity, attachment,
vascularity, regeneration
5. Properties of synovial joints: **Hyaline cartilage, joint capsule, synovial
membrane, synovial fluid, ligaments**
-Involve movement between joints
The surface of the joint is covered by a fluid filled capsule.
-The synovial fluid is trapped under the synovial membrane and acts as a
lubricant between the bones.
-Cartilage at the ends of the bone acts as a cushion and shock absorber.
6. 3 protein fibers in connective tissues: collagenous fibers, elastic fibers, and
reticular fibers.
7. chondroitin sulfate: provides support and adhesiveness in cartilage, bone,
skin, and blood vessels
8. Sacrum— illium: answer
9. Keratin: A fiber protein that is the principal component of hair, skin, and nails
10. Sweat glands location and function: Eccrine glands: help to maintain
homoeostasis, primarily by stabilizing body temperature. Smaller glands and
excretes on top of skin ((feet, forehead, cheeks)
Apocrine glands: continuously secrete a fatty sweat into the gland tubule. ((armpit,
groin, nipple area)
11. Hard palate bone: -formed by maxilla and palatine bones
12. The shaft of the bone is called: End-> Epiphysis
Middle/shaft -->>diaphysis
13. Articular process of bone: limits rotation
