Which of the following is purely a motor nerve?

Abducens nerve is a small somatic motor nerve (either of the sixth pair of cranial nerves), which supply the lateral rectus muscle of the eye. Thus, the correct answer is option C.

Which is purely motor nerve?

Three purely motor nerves that innervate the muscles of the eye are collectively called oculomotor nerves and comprise the oculomotor nerve (III), the trochlear nerve (IV), and the abducens nerve (VI).

Which of the following cranial nerves is purely a motor nerve?

Cranial nerves III, IV, VI, XI, and XII are pure motor nerves.

Which of the following cranial nerves is purely a motor nerve quizlet?

The optic (II), vestibulocochlear (VIII), and olfactory (I) nerves are purely sensory, whereas the oculomotor (III), trochlear (IV), abducens (VI), accessory (XI), and hypoglossal (XII) nerves are purely motor.

What are motor nerves?

Motor nerves.

These nerves control your movements and actions by passing information from your brain and spinal cord to your muscles.

What nerve is responsible for hearing?

The vestibular nerve is primarily responsible for maintaining body balance and eye movements, while the cochlear nerve is responsible for hearing.

Which one of the following is an example of motor nerve?

the optic nerve of the eye. Motor nerves are those nerves that carry the messages in the form of a response from the brain or the spinal cord to other parts of the body such as the muscles and glands. Eg. nerves of the muscles of the eyeball.

What is the function of trigeminal nerve?

The trigeminal nerve is the largest and most complex of the 12 cranial nerves (CNs). It supplies sensations to the face, mucous membranes, and other structures of the head. It is the motor nerve for the muscles of mastication and contains proprioceptive fibers.

What is the main function of CN I?

Function. The cranial nerves provide motor and sensory supply mainly to the structures within the head and neck. The sensory supply includes both “general” sensation such as temperature and touch, and “special” senses such as taste, vision, smell, balance and hearing.

What nerve controls eye movement?

Cranial nerves III (CNIII) (oculomotor), IV (trochlear), and VI (abducens) control the position of the eyeballs; CNIII influences the position of the eyelids and the size of the pupils.

Which of the following nerves is purely sensory quizlet?

The only three cranial nerves that are purely sensory neurons include Olfactory (smell), Optic(sight), and Acoustic (hearing).

Which cranial nerve controls muscles that would allow one to smile and cry?

Facial Nerve or Cranial Nerve VII

The most important nerve controlling muscles of facial expression, including those involved in a smile, is unsurprisingly called the facial nerve, also known as cranial nerve VII.

What are the functions of motor nerve?

A motor nerve is a nerve located in the central nervous system (CNS), usually the spinal cord, that sends motor signals from the CNS to the muscles of the body.

What happens if motor nerves are damaged?

Motor nerve damage is most commonly associated with muscle weakness. Other symptoms include painful cramps, fasciculations (uncontrolled muscle twitching visible under the skin) and muscle shrinking. Sensory nerve damage causes various symptoms because sensory nerves have a broad range of functions.

What does a motor nerve do?

Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.
