Spinal Cord, Nerves, and the Brain All nerves ultimately connect to the brain. There are basically two major types of nerves: sensory and motor. Sensory nerves send information such as touch, temperature, and pain to the brain and spinal cord.

- At regular intervals, it gives off a pair of spinal. nerves that receive sensory input from the skin, muscles, bones, joints, and viscera, and that issue motor commands back to muscle. and gland cells. The spinal cord is a component of the central nerv-. ous system and the spinal nerves a component of the peripheral.

- The dorsal root is the part of the peripheral nervous system that picks up sensory signals and sends the signal through the nerve to the brain.

Spinal cord injury Spinal cord injury. The spinal cord relays messages between the brain and the peripheral nerves. The spine consists of the spinal cord, which is a group of nerves that are protected by the individual vertebrae of the spine. The main function of the spinal cord is to send signals from the brain to other regions of the body. It is the main messenger throughout the body. A spinal cord injury (SCI) is damage to the spinal cord that causes changes in its function, either temporary or permanent. These changes translate into loss of muscle function, sensation, or autonomic function in parts of the body served by the spinal cord below the level of the lesion.

- Outside the vertebral column, the spinal nerves divide into branches. The dorsal ramus: Contains nerves that serve the dorsal portions of the trunk carrying visceral motor, somatic motor, and sensory information to and from the skin and muscles of the back.

- 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.

Structure and Function: Brain, Spinal Cord, and Nerves Structure of the spinal cord. The spinal cord has a core of grey matter containing nerve cell bodies, dendrites, and supporting cells. Surrounding the grey matter is white matter containing columns of nerve fibres that carry signals to and from the brain along the length of the spinal cord.

- Spinal Nerves. Nerves called the spinal nerves or nerve roots, branch off the spinal cord and pass out through a hole in each of the vertebrae called the foramen. These nerves carry information from the spinal cord to the rest of the body, and from the body back up to the brain.

The Ascending Tracts In this article, we shall look at the anatomy of the ascending tracts, and consider their clinical implications. The dorsal column-medial lemniscal pathway (DCML) carries the sensory modalities of fine touch (tactile sensation), vibration and proprioception. Its name arises from the two major structures that comprise the DCML. In the spinal cord, information travels via the dorsal (posterior) columns.

Spinal nerve 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. These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine.

Ch 13: Spinal Cord and Spinal Nerves The spinal cord and spinal nerves contribute to homeostasis by providing quick, reflexive responses to many stimuli. The spinal cord is the pathway for sensory input to the brain and motor output from the brain. spinal cord reflex quick, automatic response to certain kinds of stimuli that involves neurons only in the spinal nerves and spinal cord

Neurons The cell bodies of the sensory neurons leading to the spinal cord are located in clusters, the dorsal root ganglia (DRG), next to the spinal cord. Their axon extends in both directions: a peripheral axon to receptors at the periphery and a central axon passing into the spinal cord.

Spinal cord injury The spinal cord coordinates the body's movement and sensation. Therefore, an injured cord loses the ability to send and receive messages from the brain to the body's systems that control sensory, motor, and autonomic function below the level of injury. Often, this results in some level of paralysis.

Nervous System sensory neurons. carry nerve impulses from peripheral body parts into brain/spinal cord; either have specialized receptor ends at tips of dendrites, or are closely associated with receptor cells; most are unipolar (but some are bipolar).

Spinal Nerves A spinal nerve is a mixed nerve, which carries motor, sensory, and autonomic signals between the spinal cord and the body.he posterior root is the afferent sensory root and carries sensory information to the brain. The anterior root is the efferent motor root and carries motor information from the brain. The spinal nerve emerges from the spinal column through an opening (intervertebral foramen) between adjacent vertebrae.

- Spinal Nerves. Nerves called the spinal nerves or nerve roots, branch off the spinal cord and pass out through a hole in each of the vertebrae called the foramen. These nerves carry information from the spinal cord to the rest of the body, and from the body back up to the brain.oth the nerves and the segments in the spinal cord are numbered in a similar way to the vertebrae. The point at which the spinal cord ends is called the conus medullaris, and is the terminal end of the spinal cord. It occurs near lumbar nerves L1 and L2.

THE APOLLO THEATRE, LONDON The Apollo Theatre was the first in London to be built in the Edwardian period, it was renovated by Schaufelberg in 1932, and a private foyer and ante room were installed to the Royal Box.The sculpted work on the stone fascia is by T. Simpson, the building is of plain brick to the neighbouring streets.he West End's Apollo Theatre has a rich and varied production history. George Edwards produced a series of successful Edwardian musical comedies, including Kitty Grey (1901), Three Little Maids and The Girl from Kays (1902).

Spinal Cord Anatomy Motor nerves control movement by carrying messages from the brain to the muscles. Sensory nerves carry messages from the sensory receptors in the body to the brain. In many places the motor nerves and sensory nerves run in pairs along side each other. There are 31 pairs of nerves that branch off the spinal cord.

Spinal Cord The front “wings” (called horns) contain motor nerve cells, which transmit information from the brain or spinal cord to muscles, stimulating movement. The back horns contain sensory nerve cells, which transmit sensory information from other parts of the body through the spinal cord to the brain.
