1. What are the two main parts of the efferent nervous system? 2. What are the two main divisions of the autonomic nervous system? 3. Name the area of the brain mainly responsible for controlling each of the following functions a) integration of spinal cord input b) maintenance of balance c) sensory perception 4. Chemoreceptors are one type of receptor used in the afferent division of the PNS. What do chemoreceptors detect? Name two other receptor types and what each receptor detects. 5. the sympathetic, parasympathetic, or both. a) Preganglionic fibers release acetylcholine b) Postganglionic fibers release acetylcholine 6. During a fight or flight response, receptors in blood vessels leading to the Gl tract bind primarily which causes the blood vessels to 7. How are lipophilic hormones transported in the blood?Explanation / Answer
1
2 two main divisions of autonomic nervous system are sympathetic and parasympathetic nervous system
3 a) Gray matter is used for integration of spinal cord
B) cerebellum is the main part that is responsible for the maintenance of balance
C) cerebral cortex is used for perception
4 these are sensitive to PH and carbon ioxide. Peripheral chemoreceptors: consists of aortic and carotid bodies. Aortic body detects changes in blood oxygen and carbon ioxide, but not PH , WHILE CAROTID body detects all three they do not desensitized
Other receptors
Mechano receptors : detect mechanical deformation of the receptors
Thermoreceptors : detect changes in temperature
Nociceptors : detect damage in the tissues whether physical or chemical damage pain receptors
Electromagnetic receptors : detect light on the retina of the eye
5 a both symathetic and parasympathetic
B parasympathetic division in postgangiolic fibers
6 alpha: norepi: constrict
7 lipophillic hormones cannot dissolve in plasma so they must travel bound to protein. The protein must unbound in order for the hormone to have any action. Since they are soluble lipids they need no receptors they just permeate the membrane of their target cell.
