The spinal cord is not uniform in diameter along its length.

Spinal cord anatomy. It has involuntary functions such as control of blood pressure body temperature and breathing as well as voluntary functions such as movement. The spinal cord is a cylindrical structure greyish-white in colour. The spinal cord is the most important structure between the body and the brain.

It carries signals between the brain and the rest of the body. The spinal cord is part of the central nervous system. The brain and spinal cord are the major components of the central nervous system CNS.

The spinal cord finishes growing at the age of 4 while the vertebral column finishes growing at age 14-18. The spinal cord extends from the foramen magnum where it is continuous with the medulla to the level of the first or second lumbar vertebrae. It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine.

The internal anatomy of the spinal cord is quite complex. The spinal cord is an important information relay and processing hub connecting the brain with the rest of the body. The gray matter which is primarily composed of nerve cell bodies has two regions on each side or butterfly wing within the cervical.

The spinal cord is a cylindrical structure of nervous tissue composed of white and gray matter is uniformly organized and is divided into four regions. The spinal cord is a part of the central nervous system. It consists of axons that transmit impulses to and from the brain or between levels of gray mater within the spinal cord.

The spinal cord arises cranially as a continuation of the medulla oblongata part of the brainstem. The spinal cord is a long bundle of nerves and cells that extends from the lower portion of the brain to the lower back. 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.

This long structure runs down the center of your back and it mediates messages between the brain and the peripheral nerves. Cervical C thoracic T lumbar L and sacral S Although the spinal cord constitutes only about 2 of the central nervous system CNS its functions are vital. These neural pathways represent the communicating highways of the CNS.

Although continuous with the brain the spinal cord begins where nervous tissue leaves the cranial cavity at the level of the foramen magnum. It is a vital link between the brain and the body and from the body to the brain. It then travels inferiorly within the vertebral canal surrounded by the spinal meninges containing cerebrospinal fluid.

The spinal cord is a slender column of nervous tissue that passes downward from the brain into the vertebral canal. To keep things simple the center of the cord consists of gray mater. Internal Anatomy of the Spinal Cord.

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. 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.

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

It transmits messages to and from the brain. The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. The spinal cord is the major conduit and reflex centre between the peripheral nerves and the brain and transmits motor information from the brain to the muscles tissues and organs and sensory information from these areas back to the brain.

It is situated inside the vertebral canal of the vertebral column. Neural pathways anatomy The central nervous system CNS contains numerous nerve fibers that group together to form pathways between its various parts. The spinal cord is primarily composed of nerves which are organized in systematic pathways also described as tracts.

It has a relatively simple anatomical course. Your spinal cord is part of the central nervous system which comprises the spinal cord and the brain. 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.

Anatomy of spinal cord. It is a long pipe-like structure arising from the medulla oblongata part of the brain consisting of a collection of nerve fibres running through the vertebral column of the backbone. 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 soft. It encloses the central canal of the spinal cord which contains cerebrospinal fluid.
