Anatomy Spinal Cord

The spinal cord is a part of the central nervous system CNS along with the brain with which it is continuous. Spinal Cord Anatomy Basically spinal cord is a long and narrow bundle of nervous tissues and support cells which extends from the base of our brain to the upper lumbar region.

The spinal cord is a cylindrical structure greyish-white in colour.

Anatomy spinal cord. It then travels inferiorly within the vertebral canal surrounded by the spinal meninges containing cerebrospinal fluid. The spinal cord is a long bundle of nerves and cells that extends from the lower portion of the brain to the lower back. The brain and spinal cord are the major components of the central nervous system CNS.

It stretches up to 40cm to 50cm with a diameter of 1 cm to 15cm. It has a relatively simple anatomical course. The spinal cord is an important information relay and processing hub connecting the brain with the rest of the body.

It transmits messages to and from the brain. The spinal cord also sends and receives impulses to and from different regions of the brain via nerve tracts. Neural pathways anatomy The central nervous system CNS contains numerous nerve fibers that group together to form pathways between its various parts.

Your spinal cord is part of the central nervous system which comprises the spinal cord and the brain. CROSS SECTION OF SPINAL CORD The spinal cord is incompletely divided into two equal parts anteriorly by a short shallow median fissure and posteriorly by a deep narrow septum the posterior median sulcus. It forms a vital link between the brain and the body.

OBJECTIVES describe the external structure of the spinal cord draw and describe the internal structure of the spinal cord draw and describe the ascending and descending tracts within. The spinal cord is not uniform in diameter along its length. Several spinal nerves emerge out of each segment of the spinal cord.

It is situated inside the vertebral canal of the vertebral column. Composed of grey matter in the center surrounded by white matter supported by neuroglia. It encloses the central canal of the spinal cord which contains cerebrospinal fluid.

It carries signals between the brain and the rest of the body. At the end of the spinal cord the cord fibers separate into the cauda equina and continue down through the spinal canal to your tailbone before branching off to your legs and feet. It runs from the brainstem to the 1st lumbar vertebra protected within the spinal canal.

The spinal cord encompasses the medulla oblongata lower part of the brainstem from the foramen magnum hole in the base of the skull to the first or second lumbar vertebrae 7. The spinal cord finishes growing at the age of 4 while the vertebral column finishes growing at age 14-18. The spinal cord is the link between the brain and all the bodys nerves 6.

SPINAL CORD ANATOMY 䡲 A notch in the inferior aspect of LOCALIZATION AND the pedicle will contribute to the boundary of the OVERVIEW OF SPINAL intervertebral foramen when CORD SYNDROMES adjacent vertebrae are articulated and Gregory Gruener José Biller through which the spinal nerve and intervertebral ABSTRACT vessels will pass. They can be located solely within the brain providing connections between several of its structures or they can link the brain and the spinal cord together. The spinal cord is soft.

The spinal cord is a slender column of nervous tissue that passes downward from the brain into the vertebral canal. Internal Anatomy of the Spinal Cord When viewed as a cross-section from above the spinal cord consists of a butterfly-shaped or thick H-shaped region of gray matter that sits in the middle of the white matter. These neural pathways represent the communicating highways of the CNS.

The spinal cord is divided into five different parts. The spinal cord is a long thin tubular structure made up of nervous tissue which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back.

In adults the spinal cord is usually 40cm long and 2cm wide. The spinal cord arises cranially as a continuation of the medulla oblongata part of the brainstem. It has involuntary functions such as control of blood pressure body temperature and breathing as well as voluntary functions such as movement.

Although continuous with the brain the spinal cord begins where nervous tissue leaves the cranial cavity at the level of the foramen magnum. It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine. Anatomy of spinal cord.

The spinal cord is basically a long bundle of nervous tissue and supporting cells located within the vertebral column that provides innervation for the trunk and limbs. A transverse section of the spinal cord reveals a distinct butterfly pattern of dark inner grey matter surrounded by the lighter colour white matter. The spinal cord is about 18 inches long and is the thickness of your thumb.

The spinal cord is part of the central nervous system CNS. The spinal cord is a cylindrical shaped bundle of nerve fibers that is connected to the brain at the brain stem. SPINAL CORD PROF DR NASARUDDIN ABDUL AZIZ Management Science University email_address 2.

During development theres a disproportion between spinal cord growth and vertebral column growth.
