An inability to extend the leg would result from a loss of function of the common peroneal nerve, a branch of the sciatic nerve. This nerve provides motor function to the muscles that extend the leg and dorsiflex the foot. Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.

Which nerve damage results in wristdrop inability to extend the hand at the wrist?
Wrist drop, characterized by the inability to extend the hand at the wrist, is primarily caused by damage to the radial nerve. This nerve controls the muscles responsible for wrist and finger extension. Injury to the radial nerve can occur due to various factors, including compression, trauma, or prolonged pressure on the arm. As a result, individuals may experience weakness or paralysis in the affected hand and wrist.
What is the function of the medial nerve?
The median nerve provides sensory and motor function to the hand and forearm. It innervates muscles involved in flexion of the wrist and fingers, as well as sensation to the palm and fingers. Injury to the median nerve can result in weakness, numbness, and tingling in the hand and fingers.
What is the name of the nerve if you unable to blink?
The nerve responsible for blinking is the facial nerve. If you are unable to blink, it could be due to damage or dysfunction of this nerve, which may result in a condition known as facial nerve palsy or Bell's palsy. Immediate medical attention is necessary if you experience sudden inability to blink.
What does the L4 nerve control?
The L4 nerve originates from the lumbar spine and supplies sensation and motor function to the thigh and inner knee. It also plays a role in controlling muscles that extend the knee joint.
Which cranial nerve if damaged causes inability to see close?
The cranial nerve that, if damaged, can cause an inability to see close objects is the oculomotor nerve (cranial nerve III). Damage to this nerve can affect the movement of the eye muscles responsible for changing focus and adjusting the shape of the lens to see objects up close.

What is the nerve for a broken forearm resulted in an inability to pronate the forearm and loss of finger movement in digits 1-3?
The symptoms of inability to pronate the forearm and loss of finger movement in digits 1-3 suggest an injury to the median nerve. The median nerve is responsible for the motor function of several muscles in the forearm and hand, including those involved in pronation and finger movements. Damage to this nerve can result from a broken forearm, particularly if there is associated trauma or swelling in the area. As a result, the affected individual may experience weakness in wrist flexion and difficulty with thumb, index, and middle finger movements.
What is the function of the medial nerve?
The median nerve provides sensory and motor function to the hand and forearm. It innervates muscles involved in flexion of the wrist and fingers, as well as sensation to the palm and fingers. Injury to the median nerve can result in weakness, numbness, and tingling in the hand and fingers.
When Trauma to a nerve of this plexus may cause a wrist drop?
Trauma to the radial nerve of the brachial plexus can cause wrist drop. This nerve controls the muscles responsible for wrist extension. Damage to the radial nerve can lead to weakness or paralysis of these muscles, resulting in the inability to lift the wrist and extend the hand.
What is the name of the nerve if you unable to blink?

What would be the result of damage to ventral root of a spinal nerve?
Would lead to loss of both sensory & motor function. Ventral ramus is the anterior division of a spinal nerve.
Which cranial nerve if damaged causes inability to see close?
The cranial nerve that, if damaged, can cause an inability to see close objects is the oculomotor nerve (cranial nerve III). Damage to this nerve can affect the movement of the eye muscles responsible for changing focus and adjusting the shape of the lens to see objects up close.
Is the olfactory nerve a function of the paranasal sinuses?
No, the olfactory nerve is responsible for the sense of smell and is not directly related to the paranasal sinuses. The olfactory nerve fibers extend into the nasal cavity where they are stimulated by odors, but the sinuses themselves do not play a direct role in the sense of smell.
Is the vagus nerve the only cranial nerve to extend beyond the head and neck region?
True
