Muscle and the Nervous System Smooth muscle, such as in the digestive system, is also controlled by the autonomic nervous system. Like heart muscle, it is not under our conscious control. The SNS is responsible for controlling voluntary body movements, such as movement of the arms and legs. It is also responsible for receiving sensory information such as touch, hearing, and sight. The SNS contains neurons that connected with the skeletal muscles, skin, and sense organs. Neurons that control skeletal muscle and organs are called motor neurons.

cranial nerve Nerves 3, 4, and 6 are all motor nerves. They supply the muscles around the eyeball and carry the impulses which move the eye. 7. Facial nerve. A mixed nerve. The motor fibers supply the facial muscles of expression and several muscles in the neck. The sensory fibers carry taste sensations from the front of the tongue.

- Ocular Movement. Oculomotor Nerve – CN III. The motor component of the oculomotor nerve innervates the ipsilateral dorsal, ventral, medial recti muscles as well as the ventral oblique muscle; these muscles are predominantly important for medial movement of each eye but also a dorso-medial and ventral movement is enabled.

Brain Anatomy Along with the spinal nerves, the cranial nerves are part of the peripheral nervous system. There are twelve pairs of cranial nerves. Cranial Nerves Involved in Smell and Vision. CN I, the olfactory nerve, is a purely sensory nerve.his nerve provides innervation for movements of the eyeball. The Cranial Nerves Involved in Speech, Hearing and Swallowing. CN V is the trigeminal nerve. The motor nucleus of this large mixed nerve originates in the pons.

- Sixth nerve palsy results from dysfunction or damage of your sixth cranial nerve, also known as the abducens nerve. This causes problems with eye movement. Sixth nerve palsy results from dysfunction or damage of your sixth cranial nerve, also known as the abducens nerve. This causes problems with eye movement. The sixth cranial nerve sends signals to your lateral rectus muscle. This is a small muscle that attaches to the outer side of your eye.

Sensory nervous system The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception.omatosensory Area 1, or S1, is for touch and proprioception in the somatosensory system. The somatosensory system feeds the Brodmann Areas 3, 1 and 2 of the primary somatosensory cortex. But there are also pathways for proprioception (via the cerebellum), and motor control (via Brodmann area 4).

- Spinal nerve. A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body. In the human body there are 31 pairs of spinal nerves, one on each side of the vertebral column.

- The sensory (afferent) division carries sensory signals by way of afferent nerve fibers from receptors in the central nervous system (CNS). It can be further subdivided into somatic and visceral divisions. The somatic sensory division carries signals from receptors in the skin, muscles, bones and joints.t includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions. The anterior horn cells, although technically part of the central nervous system (CNS), are sometimes discussed with the peripheral nervous system because they are part of the motor unit.

- The radial nerve is responsible for innervating the wrist extensors, which control the position of the hand and stabilize the fixed unit. It originates from the posterior cord of the brachial plexus (C6-8). At the elbow, motor branches innervate the brachioradialis and extensor carpi radialis longus muscles.

Cranial Nerve Palsy It sends visual information from the eye to the brain. The third cranial nerve is called the oculomotor nerve. It is involved with eye movement, eyelid movement, and the function of the pupil and lens. The fourth cranial nerve is called the trochlear nerve and the sixth cranial nerve is called the abducens nerve.

Cranial Nerves Key Points. 1  Cranial nerve XI is responsible for tilting and rotating the head, elevating the shoulders, and adducting the scapula. 2  Most of the fibers of the accessory nerve originate in neurons situated in the upper spinal cord. 3  Due to its unusual course, the accessory nerve is the only nerve that enters and exits the skull.

Cochlear nerve The cochlear nerve carries auditory sensory information from the cochlea of the inner ear directly to the brain.The other portion of the vestibulocochlear nerve is the vestibular nerve, which carries spatial orientation information to the brain from the semicircular canals.n terms of anatomy, an auditory nerve fiber is either bipolar or unipolar, with its distal projection being called the peripheral process, and its central projection being called the axon; these two projections are also known as the peripheral axon and the central axon, respectively.

Somatic nervous system For the musician known as Somatic, see Hahn Rowe. The somatic nervous system (SoNS or voluntary nervous system) is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements.The SoNS consists of afferent nerves and efferent nerves.fferent nerves are responsible for relaying sensation from the body to the central nervous system (CNS); efferent nerves are responsible for sending out commands from the CNS to the body, stimulating muscle contraction; they include all the non-sensory neurons connected with skeletal muscles and skin.

Introduction to Psychology âPSY101 WHAT IS PSYCHOLOGY? The somatic nervous system (SNS) is the portion of the nervous system responsible for voluntary body movement and for sensing external stimuli.All five senses are controlled by this system. The SNS is a sub-part of the peripheral nervous system.he somatic nerve system controls all five senses. Heat and pain are all transmitted by afferent neurons. The central nervous system consists of the brain and spinal cord. Afferent neurons carry impulses from sense organs to the brain, while efferent neurons carry impulses from the brain to the muscles.

Sixth nerve palsy From Wikipedia, the free encyclopedia. Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye.ecause the nerve emerges near the bottom of the brain, it is often the first nerve compressed when there is any rise in intracranial pressure. Different presentations of the condition, or associations with other conditions, can help to localize the site of the lesion along the VIth cranial nerve pathway.

The Facial Nerve (CN VII) In this article, we shall look at the anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches. The facial nerve is associated with the derivatives of the second pharyngeal arch.Motor: Innervates the muscles of facial expression, the posterior belly of the digastric, the stylohyoid and the stapedius muscles.Sensory: None.ranches of the facial nerve are responsible for innervating many of the muscles of the head and neck. All these muscles are derivatives of the second pharyngeal arch. The first motor branch arises within the facial canal; the nerve to stapedius.
