Which cranial nerve innervates the ear?
The cranial nerve that innervates the ear is the vestibulocochlear nerve (CN VIII). It has two branches: the vestibular nerve that controls balance and the cochlear nerve that controls hearing.
What is an abducent nerve?
An abducent nerve is a nerve which controls the lateral rectus muscle in the eye.
What nerve splits into the common fibular and tibial nerves?
The sciatic nerve splits into the common fibular (peroneal) and tibial nerves in the thigh region. This occurs just above the knee, with the common fibular nerve wrapping around the fibular head and the tibial nerve passing beneath the gastrocnemius muscle.
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 nerve that controls tear glands?
The lacrimal nerve, a branch of the ophthalmic nerve (which is a branch of the trigeminal nerve), controls the tear glands. It provides sensory innervation to the lacrimal gland, which is responsible for producing tears in the eye.
Why does the gastrocnemius muscle contract after stimulating the sciatic nerve?
The gastrocnemius muscle contracts after stimulating the sciatic nerve because the sciatic nerve supplies motor signals to the gastrocnemius muscle, causing it to contract. The stimulation of the sciatic nerve triggers the release of neurotransmitters that lead to the contraction of the muscle fibers in the gastrocnemius.
What is the effector of the Achilles reflex?
gastrocnemius muscle
Affecting the gastrocnemius muscle which of these is a real canine peripheral nerve disorder?
Dancing Dobermann disease
What cranial nerve controls the ears?
auditory nerve
What nerve controls quadriceps muscle group?
Femoral nerve
Which cranial nerve innervates the ear?

What is an abducent nerve?
An abducent nerve is a nerve which controls the lateral rectus muscle in the eye.
What primary nerve that controls breathing is found in which nerve plexus?
The primary nerve that controls breathing is the phrenic nerve, which arises from the cervical nerve plexus located in the neck region.
Is the endocrine system controls the body through nerve impulses?
The nervous system controls the body through nerve impulses. The endocrine system controls the body through hormones.
Cranial nerve for sense of hearing?
The vestibulocochlear cranial nerve controls hearing.
Which cranial nerve controls the heart and lungs?
CN X (Vagus)
What nerve splits into the common fibular and tibial nerves?
The sciatic nerve splits into the common fibular (peroneal) and tibial nerves in the thigh region. This occurs just above the knee, with the common fibular nerve wrapping around the fibular head and the tibial nerve passing beneath the gastrocnemius muscle.
