Functions in many ways: Involved in sensory and motor innervation of body inferior to the head (through spinal nerves) Provides a 2-way conduction pathway for signals between body and brain Regulates: Hypothalamus The Limbic System Composed of nerve tracts to and from the brain (these tracts cross over left to right and right to left) May be regarded as an extension of the spinal cord Almost all of the cranial nerves arise from this region Contains control centers for many subconscious activities Respiratory rate Heart rate. The spinal nerves comes out of the spine, and the cranial nerves come out of the brain directly. This is the most important cranial nerve because it innervates all of the organs in the thoracic and abdominal cavities. Enters the skull through foramen magnum. It just supplies the shoulder muscles. XI. PowerPoint Presentation Last.

Cranial neuropathies are caused by damage to one or more cranial nerves. These are nerves that arise directly from the brain and affect movement and sensation in the eyes and face. The causes of cranial neuropathies include poorly controlled diabetes or high blood pressure, head injuries, infections, strokes, and brain tumors Pupillary light reflex - retina of the eye is the receptor; many CNS centers involved - tests function of the sensory (afferent) optic nerve (= cranial nerve I) and of efferent oculomotor nerve (= cranial nerve III) - effector muscles are smooth muscles of the iris; - absence of reflex is late indication of severe trauma or deterioration of the.

The key difference between Cranial and Spinal Nerves is that the cranial nerves originate from the brain and carry nerve impulses to the eyes, mouth, face and other parts of the head region while the spinal nerves originate from the spinal cord and carry nerve impulses to the other parts of the body..

Talking to you about the cranial nerves and the spinal nerves. And this will set up a tour of the cranial nerves that I'd like to show you in the laboratory with a real human brain. Well, my learning objectives for you are first, I want you to be able to discuss the surface features of each of the three subdivisions of the brain stem In addition to the 31 pairs of spinal nerves mentioned in the slides on the spinal cord, there are 12 pairs of cranial nerves that attach to the brain: I. The olfactory nerve carries sensory input for smell. II. The optic nerve carries sensory input for vision. III. The oculomotor nerve controls muscles of the eye and eyelid. IV 3.5.3 Cranial Nerves. The cranial nerve which is present in the posterior triangle of the neck is that of the accessory nerve. Accessory Nerve. The spinal accessory nerve is the eleventh cranial nerve. It is a motor nerve (somatic motor) innervating two muscles—the sternocleidomastoid and trapezius. It has two components—a spinal. The human body has 12 pairs of cranial nerves that control motor and sensory functions of the head and neck. The anatomy of cranial nerves is complex and its knowledge is crucial to detect pathological alterations in case of nervous disorders. Therefore, it is necessary to know the most frequent pathologies that may involve cranial nerves and recognize their typical characteristics of imaging

The spinal component of the accessory nerve is made up of roots from the sixth and seventh cervical vertebrae, which are in your neck. Once the nerve is formed, it runs up to enter the cranial cavity through an opening called the foramen magnum, which is a large opening near the back of the skull Spinal nerves. In humans, 31 pairs of spinal nerves arise from the cord and exit from the vertebral column to serve the body area close by. Cauda equina. The collection of spinal nerves at the inferior end of the vertebral canal is called cauda equina because it looks so much like a horse's tail.

Lyons, in Handbook of Clinical Neurology, 2013. Abstract. We review the supranuclear control centers and pathways leading to individual cranial nerve nuclei in the brainstem. We discuss horizontal and vertical gaze and their abnormalities, and review the cranial nerves which subserve eye movements, III, IV, VI, including their clinical testing The cranial nerves for each of these are: 2 for the midbrain (CN 3 & 4), 4 for the pons (CN 5-8), and 4 for the medulla (CN 9-12). It is important to remember that cranial nerves never cross (except for one exception, the 4th CN) and clinical findings are always on the same side as the cranial nerve involved This information is then carried into the brain and spinal cord through cranial and spinal nerves. 2. Integrative function. The nervous system integrates (processes) sensory information by analyzing and storing some of it and by making decisions for appropriate responses.
