If talking about the skull, the dorsal side is the top. [38] The ventral (from Latin venter 'belly') surface refers to the front, or lower side, of an organism. [38] For example, in a fish, the pectoral fins are dorsal to the anal fin, but ventral to the dorsal fin. The terms are used in other contexts; for example dorsal and ventral gun ...
Hence, what is technically a transverse (orthogonal) section with respect to the body length axis of a rat (dividing anterior from posterior) may often be referred to in rat neuroanatomical coordinates as a coronal section, and likewise a coronal section with respect to the body (i.e. dividing ventral from dorsal) in a rat brain is referred to ...
The fibers of the ventral spinocerebellar tract then enters the cerebellum via the superior cerebellar peduncle. This is in contrast with the dorsal spinocerebellar tract (C8 - L2/L3), which only has 1 unilateral axon that has its cell body in Clarke's column (only at the level of C8 - L2/L3). Originates from ventral horn at lumbosacral spinal ...
Superior to the junction, the terminology is the same as in animals with linear nervous systems; dorsal is synonymous with superior and ventral is synonymous with inferior. However, inferior to the midbrain-diencephalic junction the term dorsal is synonymous with posterior and ventral is synonymous with anterior. [1]
The dorsal (posterior) cavity and the ventral (anterior) cavity are the largest body compartments. The dorsal body cavity includes the cranial cavity, enclosed by the skull and contains the brain, and the spinal cavity, enclosed by the spine, and contains the spinal cord. [1]
Dorsal striatum (a.k.a. neostriatum) Putamen; Caudate nucleus; Ventral striatum. Nucleus accumbens; Olfactory tubercle; Globus pallidus (forms nucleus lentiformis with putamen) Ventral pallidum; Subthalamic nucleus; Basal forebrain. Anterior perforated substance; Substantia innominata; Nucleus basalis; Diagonal band of Broca; Septal nuclei ...
The dorsal ramus of spinal nerve, posterior ramus of spinal nerve, or posterior primary division is the posterior division of a spinal nerve.The dorsal rami provide motor innervation to the deep (a.k.a. intrinsic or true) muscles of the back, and sensory innervation to the skin of the posterior portion of the head, neck and back.
The location of motor neurons in the anterior grey column of the spinal cord. The anterior grey column, (also known as the anterior horn of spinal cord and anterior cornu) is broad and of a rounded or quadrangular shape. Its posterior part is termed the base, and its anterior part the head, but these are not differentiated from each other by ...
