What spinal group controls diaphragm?
The phrenic nerve, which arises from the C3-C5 nerve roots in the cervical spine, innervates the diaphragm muscle and controls its function. Dysfunction of the phrenic nerve can impair breathing and lead to respiratory issues.
What two nerves innervate the quadriceps and hamstrings?
The quadriceps are primarily innervated by the femoral nerve, which provides motor function to this muscle group. In contrast, the hamstrings are predominantly innervated by the sciatic nerve, specifically its tibial and common fibular branches. These nerves play crucial roles in the extension of the knee (quadriceps) and the flexion of the knee and extension of the hip (hamstrings).
What is an abducent nerve?
An abducent nerve is a nerve which controls the lateral rectus muscle in the eye.
What do the nerve and muscle cells do?
controls your body and your movements
Which nerve controls the movement of the lattisimus dorsi muscle?
The muscle is innervated by Thoracodorsal nerve, from the posterior cord of brachial plexus.
What nerve controls gastrocnemius?
The tibial nerve controls the gastrocnemius muscle. It is a branch of the sciatic nerve and innervates the muscles of the posterior compartment of the leg, including the gastrocnemius.
Function of abducens nerve?
The abducens nerve (cranial nerve VI) controls the lateral rectus muscle of the eye, which is responsible for abducting (moving the eye away from the nose) the eye. Dysfunction of the abducens nerve can result in horizontal double vision (diplopia) and difficulty moving the affected eye laterally.
What extends the knee and flexes the thigh?
The Femoral nerve. (The motor branches innervate anterior thigh muscles - quadriceps, which flex the thigh and extend the knee.)
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.
What is the Trochlea of the superior oblique muscle of the eye?
The Trochlea Nerve (cranial nerve 4) controls the superior oblique muscle of the eye. It turns the eye laterally and downwards.
Which facial nerve controls which side of the face?
nerves do not control face movement, muscle does
What nerves control the quadriceps?
The femoral nerve.
