The spinal cord is part of the central nervous system (CNS), which extends caudally and is protected by the bony structures of the vertebral column. It is covered by the three membranes of the CNS, i.e., the dura mater, arachnoid and the innermost pia mater.

2023年7月24日 · The spinal cord is a long cylindrical extension of the central nervous system within the vertebral column's cavity. It is approximately 42.3 cm in length in males and 38.9 cm in females. Even though the spinal cord is almost symmetrical, it is enlarged in a fusiform shape in two regions in the form of cervical and lumbosacral enlargements. In ...

2025年1月22日 · The spinal cord is a long, cylindrical structure that extends from the brainstem to the lower back, acting as the main pathway for transmitting information between the brain and the rest of the body. It is made up of nerve fibers and surrounded by …

2023年1月8日 · The spinal meninges are three membranes that surround the spinal cord – the dura mater, arachnoid mater, and pia mater. They contain cerebrospinal fluid, acting to support and protect the spinal cord.

2023年6月26日 · The spinal cord is a tubular structure composed of nervous tissue that extends from the brainstem and continues distally before tapering at the lower thoracic/upper lumbar region as the conus medullaris. The spinal cord is anchored distally by the filum terminale, a fibrous extension of the pia mater anchoring the spinal cord to the coccyx. [1] .

2019年11月12日 · Spinal cord functions include carrying signals between the brain and the rest of the body. This article covers the key anatomy of the spinal cord and its functions. It also provides...

2025年1月31日 · The spinal cord is a major component of the central nervous system (CNS) that forms the vital link between the brain and most of the body. Its 31 spinal segments connect the CNS to the organs and tissues of the neck, torso, and limbs.

Knowledge of spinal cord functional anatomy makes it possible to diagnose the nature and location of cord damage and many cord diseases. The spinal cord is divided into four different regions: the cervical, thoracic, lumbar and sacral regions (Figure 3.1). The different cord regions can be visually distinguished from one another.

2019年9月23日 · It is an ovoid shaped column of nerve tissue that extends from the brain down to the second lumbar vertebrae. It allows us to control our arms, legs, and our bathroom habits, among many other things. The spinal cord is enclosed in protective tissues called the meninges. The meninges form a protective sack around the spinal cord.

2024年6月28日 · The spinal cord is the part of the central nervous system found within the vertebral column's spinal canal. The cord extends from the corticomedullary junction at the foramen magnum of the skull down to the tip of the conus medullaris within the lumbar cistern.

The spinal cord is a slender column of nervous tissue that passes downward from the brain into the vertebral canal. Although continuous with the brain, the spinal cord begins where nervous tissue leaves the cranial cavity at the level of the foramen magnum. The spinal cord is not uniform in diameter along its length.

2019年8月23日 · In this article, we will discuss the differences between grey and white matter of the spinal cord. We’ll also cover the protective coating of the spinal cord and the blood vessels of the spinal cord. More information on the tracts of the spinal cord can be found in the ascending and descending tract articles.

2024年9月10日 · The spinal cord is a cylindrical, well-organized structure. It begins at the foramen magnum as a continuation of the medulla oblongata at the base of the skull. It is located within the vertebral or spinal canal. In men, it extends up to 45 cm, and in women, up to 43 cm.

2024年10月2日 · This atlas of human anatomy describes the spinal cord through 18 anatomical diagrams with 270 anatomical structures labeled. It was designed particularly for physiotherapists, osteopaths, rheumatologists, neurosurgeons, orthopedic surgeons and general practitioners, especially for the study and understanding of medullary diseases.

Anatomy of the Spinal Cord. The spinal cord is the main pathway of communication between the brain and the rest of the body. It is a long, thick, fragile structure that extends downward from the base of the brain. The cord is protected by the back bones (vertebrae) of the spine (spinal column). The vertebrae are separated and cushioned by disks ...
