What 3 structures are only innervated by the sympathetic nervous system?
-The skin(sweat glands and arrectopili muscles attached to the hair follicles) -the adrenal medulla - and all blood vessels(except of the external genitalia)
Are the structures that specifically exhibit vasomotor tone mostly under sympathetic control?
True
The neurotransmitter used at cholinergic synapse is?
The neurotransmitter is called acetylcholine. Cholinergic receptors are of two kinds: nicotinic receptors, which are situated in striated muscles and muscarinic receptors, which are situated in parasympathetically innervated structures.
Inflamation of facial nerves-?
People suffering from the facial nerve paralysis usually suffer from the inflammation of facial nerves.
What are the two division of nervous system?
The nervous system is initially divided into the central nervous system (CNS) (brain and spinal cord) and the peripheral nervous system (PNS) (pretty much all nerves and related structures that do not reside in the brain or spinal cord). The PNS is then divided into two two divisions known as the somatic division (voluntary) and the autonomic division (involuntary). The autonomic nervous system is then once more divided into the sympathetic and parasympathetic divisions.
Does the skin receive parasympathetic innervation?
Skin structures get innervation from sympathetic out flow. But the neurotransmitter is acetylcholine. So functionally the nerve supply is parasympathetic.
Which structures would not be innervated by the sympathetic nervous system A. skeletal muscle B. glands C. smooth muscle D. cardiac muscle?
skeletal muscles
How can sympathetic and parasympathetic fibers exert antagonistic effects?
Sympathetic fibers convey impulses that stimulate our "fight or flight" response. Parasympathetic are just the opposite, you might say they are for "rest and digest". They are both firing at the same time but depending on your environment and emotional state, one will dominate over the other. Sympathetic and parasympathetic fibers release different neurotransmitters, which bind to different receptors. Three structures that receive sympathetic innervation are the adrenal glands, arrector pilli muscles, and sweat glands.
What are the three major structures of the cardiovascular system?
The three major structures of the cardiovascular system the heart, the arteries and the veins.
What 3 structures are only innervated by the sympathetic nervous system?
-The skin(sweat glands and arrectopili muscles attached to the hair follicles) -the adrenal medulla - and all blood vessels(except of the external genitalia)
Are the structures that specifically exhibit vasomotor tone mostly under sympathetic control?
True
What are the structures associated with the cardiovascular system and the respiratory system?
the structers are a lot of thing yeah
What is a Sympathomimetic?
Denoting a drug that mimics the effects of stimulation of organs and structures by the sympathetic nervous system.
What are the fibers that enter and leave the sympathetic chain without synapsing form structures are called?
Splanchnic nerves
The neurotransmitter used at cholinergic synapse is?
The neurotransmitter is called acetylcholine. Cholinergic receptors are of two kinds: nicotinic receptors, which are situated in striated muscles and muscarinic receptors, which are situated in parasympathetically innervated structures.

Hypovolemic shock is defined as inadequate circulation of blood through one or more organs or structures or the collapse of the?
cardiovascular system
