Its posterior part is termed the base, and its anterior part the head, but these are not differentiated from each other by any well-defined constriction. E) collaterals. It is separated from the surface of the medulla spinalis by a layer of . The Structure Of The Anterior Horn Of The Spinal Column The spinal cord's anterior (and posterior) horn is composed of gray matter. E) funiculi. intermediolateral cell column Lateral horn. The gray commissure of the spinal cord is in turn divided by a posterior region and an anterior region. See answer (1) Best Answer. 35) The large anterior gray horns of the spinal cord contain mainly 1- Anatomy of spinal cord. 4- Spinal cord at different levels. The gray matter of the spinal cord is a region that is composed primarily of bodies of neurons and supporting cells. White Matter The white matter of the spinal cord is arranged in three columns or tracts. 33) The white matter of the spinal cord is mainly A) unmyelinated axons. It contains pathways that connect the brain with the rest of the body.. Keep learning about the white and grey matter of the spinal cord using our spinal cord diagram . D) nerve tracts. It contains cell bodies of preganglionic neurons of the sympathetic nervous system. 31) The anterior horns of the spinal cord contain mainly A) sensory nuclei. Anatomy: The Anterior Horn Cells of the Spinal Cord Anterior horn cells (-motor neurons), located in the anterior gray matter of the spinal cord, are found at every segment and are concentrated in the cervical and lumbosacral enlargements. anterior, posterior, and lateral. E) white commissures. The anterior horn runs the length of the spinal cord and varies in size according to the central cavity that houses the spinal cord. d The white matter of the spinal cord contains A) bundles of axons with common origins, destinations, and functions. The large anterior gray horn (otherwise the ventral horn) contains the cell bodies of motor neurons, which sends axons via the ventral roots of the spinal nerves to innervate the striated muscles. The gray horns of the spinal cord contain mainly. The anterior horns of the spinal cord contain mainly. Ventral Horn is the head of the anterior horn that comprises motor neurons that transmit impulses to the skeletal muscle. It plays a large role in sending impulses to the skeletal muscles but is also connected to other parts of the spinal cord, including the posterior grey column. The white matter of the spinal cord is mainly: myelinated and unmyelinated axons.
