What else can I help you with?
Autonomic nerves innervate what three things?
Smooth muscle Cardiac muscle Gland
What does the spinal nerves from the sacral region of the cord innervate?
leg
Why is the face not included in the dermatome distribution?
The face is not included in typical dermatome distribution because the cranial nerves innervate the face instead of spinal nerves. The cranial nerves, specifically the trigeminal nerve (CN V), provide sensory innervation to the face.
What nerves innervate the muscles of the calf?
Mainly tibial nerve, and superficial peroneal
What is the difference between peripheral nerves and cranial nerves?
cranial nerves are nerves which arise from different parts of brain that are paired and 12 pair and 24 in number. peripheral nerves are neurons that exists out side brain and spinalcord and make up peripheral nerve system.
Where are ther nerves to the colon located in the spine?
The nerves that innervate the colon originate from the spinal levels T10-L2. These nerves form the superior mesenteric plexus, which supplies the colon with autonomic innervation.
Where are the majority of parasympathetic fibers found?
The majority of parasympathetic fibers are found in the cranial nerves (specifically the oculomotor, facial, glossopharyngeal, and vagus nerves) and in the sacral spinal cord (S2-S4). These fibers innervate various organs such as the heart, lungs, and digestive system, promoting rest and digestion.
What nerve is carrying the afferent and efferent impulses during the patellar reflex?
The nerves innervate the quadriceps. The afferent nerves are the muscle spindles and the efferent are the motor neurons.
How many nerves are in the leg?
There are numerous nerves in the leg, including the sciatic nerve, femoral nerve, and tibial nerve. These nerves innervate different areas of the leg, providing sensation and motor function.
What is example of efferent nerves?
The somatic nervous system contains efferent nerves, such as the motor neurons that control voluntary movement of muscles. For example, the efferent nerves that innervate the skeletal muscles in your arms to produce movement when you reach for something are part of the somatic efferent nerves.
Can sciatica cause referred pain in the abdomen?
I am not sure exactly what nerves innervate the back, but I would assume that it could definitely refer to the abdomen.
Is it true that splanchnic nerves are mixed motor and sensory nerves?
Yes, splanchnic nerves are primarily composed of autonomic (motor) fibers that innervate the viscera (organs) of the abdomen. They carry information from the organs to the central nervous system but are not primarily sensory in nature.
