It is covered by the three membranes of the CNS, i.e., the dura mater, arachnoid and the innermost pia mater The brain and the spinal cord are the central nervous system, and they represent the main organs of the nervous system. Define a reflex and reflex arc, and describe the components of the reflex arc The spinal cord study is one of the most complex yet quite a fascinating part of the nervous system. Describe the spinal nerves: formation, branches and distribution via plexuses. Part of the book series: Neuroscience The spinal cord is the conduit between the brain and the rest of the body, sending motor commands from the motor cortex to the muscles and sensory information from the afferent fibers to the sensory cortex. The brain and spinal cord together make up the central nervous system The spinal cord is part of the central nervous system. It extends from the Anatomy and Physiology of the Spinal Cord. Spinal Reflexes. It is a continuation of the medulla and passes out of the cranial vault through the foramen magnum and continues to run caudally in the vertebral canal, formed from the adjacent vertebral foramina In certain instances, the spinal cord can act without signals from the brain, as it can independently coordinate reflexes using reflex arcs 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. The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum Describe the internal anatomy of the spinal cord. Define Dermatome and describe its significance The spinal cord consists of a densely packed column of nerve tissue, which runs from the brainstem to around L in adults. Indicate on a diagram of a cross-section of the spinal cord, the ascending and descending tracts. Chapter. Define Dermatome and describe its significance. Control movements of trunk & limbs. Controlled by spinal The spinal cord has two main functions: transmitting nerve impulses between the brain and body, and integrating sensory information to trigger spinal reflexes. Describe the spinal nerves: formation, branches and distribution via plexuses. Chapter Spinal Cord and Spinal Nerves I. Spinal Cord A. General StructureThe spinal cord extends from the _____ to the _____Why is the spinal cord shorter than The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the brain (the medulla specifically).

Its complex connections, the development defects, the lesions, and clinical presentation are quite overwhelming and warrants a better understanding of its anatomical and physiological nature Questions.
