What else can I help you with?
Are most innervated blood vessels receive only sympathetic nerve fibers?
No, most blood vessels are innervated by both sympathetic and parasympathetic nerve fibers. However, sympathetic nerve fibers typically have a more pronounced effect on blood vessel activity compared to parasympathetic fibers.
Is the vagus nerve sympathetic or parasympathetic?
The vagus nerve is parasympathetic.
Is the vagus nerve sympathetic or parasympathetic in its function?
The vagus nerve is primarily parasympathetic in its function.
Does your brain have nerve endings?
No, the brain itself does not have nerve endings. Nerve endings are found in other parts of the body, such as the skin, that send signals to the brain.
Are there nerve endings in the brain?
No, the brain itself does not have nerve endings. Nerve endings are found in other parts of the body, such as the skin and organs, but not in the brain itself.
Are most innervated blood vessels receive only sympathetic nerve fibers?
No, most blood vessels are innervated by both sympathetic and parasympathetic nerve fibers. However, sympathetic nerve fibers typically have a more pronounced effect on blood vessel activity compared to parasympathetic fibers.
What parts of the nervous system controls digestion?
The parasympathetic nervous system is responsible for digestion. The GI tract is innervated by the Gastric nerve, otherwise known as the Vagus nerve.
Is acetylcholine the substance released by axonal endings of the somatic efferent fibers and by the parasympathetic nerve fiber endings?
Yes, it does. In contrast, the sympathetic nerves release adrenaline
Is the vagus nerve sympathetic or parasympathetic?
The vagus nerve is parasympathetic.
What nerves supply the innervation of the bladder and the internal sphincter?
The bladder is innervated by the parasympathetic fibers of the pelvic splanchnic nerves (S2-S4) which stimulate contraction of the detrusor muscle. The internal urethral sphincter is innervated by sympathetic fibers from the hypogastric nerve, which cause it to contract and prevent urine leakage.
What three muscles are innervated by nerves?
Three muscles that are innervated by specific nerves include the biceps brachii, which is innervated by the musculocutaneous nerve; the quadriceps femoris, innervated by the femoral nerve; and the diaphragm, which is innervated by the phrenic nerve. Each of these nerves plays a crucial role in controlling muscle movement and function.
Which nerve innervates the gallbladder?
The gallbladder is primarily innervated by the vagus nerve (cranial nerve X), which provides parasympathetic stimulation. Additionally, sympathetic innervation comes from the celiac plexus, particularly through the greater splanchnic nerve. This dual innervation helps regulate gallbladder contraction and bile release.
Is the vagus nerve sympathetic or parasympathetic in its function?
The vagus nerve is primarily parasympathetic in its function.
What do nerves have to do with exocytosis?
Nerves nerve endings that release neurotransmitters (eg. Acetylcholine) that initiate action potential to the innervated organ causing dpolarization, etc. This can be released through exocytosis.
Which nerve supplies the pelvic floor?
The pudendal nerve (part of the somatic nervous system, voluntary control) innervates the pelvic floor. It also innervates the external urethral sphincter; the internal urethral sphincter is innervated by the pelvic nerve (part of the parasympathetic nervous system, involuntary control).
Which nerve conveys parasympathetic signals to the heart?
The Vegal Nerve conveys parasympathetic signals to the heart
Flexor muscles in the anterior arm are innervated by what nerve?
The musculocutaneous nerve
