Question

Name: 1. Which type of neuron is found in an autonomic ganglion? sera,-- meta- (Hint: somatic, visceral, sensory, motor) Keeping the body cool while providing oxygen& nutrients to active muscles during exercise is a result of fiber stimulation innervating sweat glands and skeletal muscles. 2. (Hint: cholinergic or adrenergic; sYMP or PSYMP: preganglionic or postganglionic) 3. Fibers that enter the sympathetic chain and leave the chain without synapsing on any neuron structures are known as nerves. Autonomic motor neurons maintain a resting level of spontaneous activity. This physiological process of homeostasis is known as 4. 5. Name two types of parasympathetic receptors that are located on postsynaptic membranes 6. A neurotransmitter producing stimulation or inhibition of a particular activity depends on: 7. Which muscle tissue type is not directly controlled by the ANS? 8. What type of response results from visceral reflexes? nvolanatsaomis motor Hint: voluntary or involuntary, autonomic or somatic; sensory or motor) . 9. What physiological term is used to correctly designate an effector that is innervated by both the parasympathetic and sympathetic divisions of the ANS? 10. Which autonomic plexus is approximately located anterior to the fifth lumbar vertebra and serves the pelvic viscera? 1.

Explanation / Answer

3. Keeping the body cool while providing oxygen and nutrients during the time of exercise is a result of cholinergic parasympathetic postganglionic fiber stimulation innervating of sweat gland and skeletal muscles.

4. It is physiological response which occurs in response to a harmful events or attack this system is very spontaneous and is called as fight and flight response.

5. A) Nicotinic receptors : these are the receptors present at the postsynaptic membrane. These are actylcholine receptors.

B) Muscarinic receptors: These are choliensterase inhibitors present on postsynaptic membrane.

7. Skeletal muscle : This muscle is somatic effectors which carry impulse from body to brain hence autonomic nervous system can not control this tissue.

9. Duel innervation: It is designated an effector which is parasympathetic and sympathetic divisions on ANS.

10. Superior mesenteric plexus: is located approximately to the fifth lumbar vertebra and serves the pelvis viscera.
