Cranial Nerve XI (eleven) is know as the spinal accessory nerve and is responsible for the action of shoulder shrugging by way of its innervation of the trapezius muscle.
The function of this cranial nerve may also be tested by asking the patient to turn their head to the left and right and by resisting this motion by placing your hand on their chin (the muscle tested in this second scenario is the Sternocleidomastoid, SCM).
What else can I help you with?
Cranial nerve for sense of hearing?
The vestibulocochlear cranial nerve controls hearing.
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 cranial nerve controls the ears?
auditory nerve
What cranial nerve is used when smelling a flower?
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
Which cranial nerve controls hearing and body balance?
The cranial nerve that controls hearing and body balance is the vestibulocochlear nerve, also known as cranial nerve VIII. It has two main branches: the cochlear branch, responsible for hearing, and the vestibular branch, responsible for balance and spatial orientation.
What is the name and number of the cranial nerve that involves shrugging the shoulders?
The Cranial Nerves that helps in shrugging of shoulder is the XI Cranial Nerve Nervus Accessorius or Accessory Nerve that innervated the Trapezius Muscle
Which cranial nerve controls the sensation of hunger and GI discomfort?
The Trigminal Nerve (V)
What is the nerve IV of the cranial nerves?
The nerve IV of the cranial nerves is the trochlear nerve. It is responsible for controlling the superior oblique muscle of the eye, which helps with downward and inward eye movements. It is the smallest cranial nerve in terms of the number of axons it contains.
What cranial nerve is involved in hyper extending and flexing the neck?
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
What system controls the sense of balance and connects the inner ear to the brain by a nerve?
The vestibular system controls the sense of balance and connects the inner ear to the brain through the vestibulocochlear nerve (also known as the 8th cranial nerve). It helps in maintaining equilibrium, spatial orientation, and coordinating eye movements with head movements.
Which cranial nerves conduct the sensory and motor impulses of the eye?
The Optical nerver or the Second Cranial nerve controls and relays information absorbed through the rods and cones of the eye. Eye movements (eye muscles), however, are controlled by several other cranial nerves including the Oculomotor, Abducens, and Trochlear nerves.
Which cranial nerve controls the heart and lungs?
CN X (Vagus)
