Hand: dorsal vs. palmer i. The ventral side of a vertebrate is generally considered its "underbelly"-- paler and less hairy than its dorsal counterpart because of fewer hair follicles and less melanin production. The ventral horns contains the cell bodies of motor neurons that send axons via the ventral roots of the spinal nerves to terminate on striated muscles. The vagus has two branches: dorsal (back) and ventral (front). The ventral is the larger cavity and is subdivided into two parts (thoracic and abdominopelvic cavities) by the diaphragm, a dome-shaped respiratory muscle. These are two anatomical terms used to describe the location of structures of the body in anatomy and embryology. The term ventral refers to the anterior (front) aspect of the embryo, while dorsal refers to the posterior (back). The following page displays the acceptable use of terminology when referring to the entire separated brain and spinal cord. Dorsal rami of spinal nerves in human anatomy With the exception of the first two cervical spinal nerves, when compared to the ventral rami, the dorsal rami of spinal nerves are shorter.

Answer (1 of 3): All the examples you gave are viable alternatives. The ventral stream projects ventro-laterally toward inferior posterior temporal cortex (posterior middle temporal gyrus) which serves as an interface between sound-based representations of speech in the superior temporal gyrus (again bilaterally) and widely distributed conceptual representations. Ventral: Pertaining to the front or anterior of any structure. The dorsal and the ventral pathway are anatomically connected to each other by several major groups of axons. Along each dorsal root is small bulge called the dorsal root ganglion (or spinal ganglion).

The white matter of the spinal cord is subdivided into dorsal (or posterior), lateral, and ventral (or anterior) columns, each of which contains axon tracts related to specific functions. The It goes down the spine and has a role in controlling our lungs, hearts (moderating heartbeats so they don't get too rapid) and stomach (where it actually aids digestion). ramus, ventral primary. Functional and Structural Anatomy of the Dorsal and Ventral Attention Systems The following paragraph shall outline the critical nodes of the dorsal and ventral attention network and describe their functional and structural anatomy. 2. In context|anatomy|lang=en terms the difference between dorsal and posterior is that dorsal is (anatomy) the top surface of foot and/or hand while posterior is (anatomy) nearer the back end; nearer the caudal end of the body in quadrupeds or the dorsal end in bipeds. On cross-section, divided into dorsal, intermediate (major part) and ventral lamina. If talking about the skull, the dorsal side is the top. For starters, the bones of the hand sit in a curved arrangement so, like the foot, it's convex on its dorsal side and concave on its palmer side.

I always correct my primatology students to use the term ventral-dorsal when they refer to the more usual animal mating position: doggy style. Deep e. Close to or away from the surface of the body 6. Beside above, what is the difference between dorsal and ventral roots? (of a knife) Having only one sharp side. In Dorsal-P6a, the volume of posterior section calculated using 2D images was greater than that calculated using 3D images (404 vs. 370 mL; p = 0.004). The ventral midbrain is composed of the cerebral peduncles (crus cerebri), which contain the pyramidal and corticopon-tine tracts. Ex: The lumbar vertebrae are caudal to the cervical vertebrae. 1. Nail - Surface anatomy. The root is ~ 1/4 th of the nail plate. As adjectives the difference between ventral and palmar is that ventral is related to the abdomen or stomach while palmar is (anatomy|not comparable) of or pertaining to the palm of the hand or comparable appendage. As you progress through a course on anatomy, you will be asked to located structures by referencing various regions of the body. Rostral and caudal are only used to describe structures within the central nervous system, above the level of the spinal cord (e.g brainstem, cerebrum and cerebellum). The penis is a male organ that is used for reproduction and urination which is located within the urogenital triangle between the perineal membrane superiorly and deep perineal fascia inferiorly. draws heavily on what is known about the functional anatomy of vision, and more recently audition, particularly the distinction that has been made between dorsal and ventral streams.
