There are some terms that are specifically used in the description of embryology, which have the potential to further complicate an already complex subject!. Ventral anatomy. A comparison of sweat gland diameter in dorsal, lateral, and ventral areas of all the body regions concluded that in dorsal area the maximum diameter was observed in abdomen dorsal followed by neck dorsal, head dorsal, thorax dorsal, and tail dorsal areas but the difference was significant (p<0.05) in the head, thorax, and tail. DESIGN: Gross and microscopic dissection was performed on 11 embalmed human cadavers. They help to avoid any ambiguity that can arise when describing the location of structures. The striatum, or corpus striatum (also called the striate nucleus), is a nucleus (a cluster of neurons) in the subcortical basal ganglia of the forebrain.The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia. Ventral is a term of location used in anatomy which means the anterior part of the body frontbelly and dorsal means the posterior part back. Thalamus is a part of the diencephalon. The anatomical terms of location are vital to understanding and using anatomy. A ventral-lateral view of the brain is rarely seen in textbooks and atlases. Projections from the lateral parabrachial nucleus to the lateral and ventral lateral periaqueductal gray subregions mediate the itching sensation. Way Yin These two terms, used in anatomy and embryology, describe something at the back (dorsal) or front/belly (ventral) of an organism.

The lateral horn of the spinal cord is the small lateral projection of grey matter located between the dorsal horn and ventral horn and contain the neuronal cell bodies of the sympathetic nervous system. In anatomy: Dorsal means back (spinal column) and Ventral is the opposite (belly and chest). Objective: Clinical observation has suggested the presence of ventral cervical extra-articular pain pathways in patients with C1-C2 joint pain. However, the existence of ventral innervation to the C1-C2 joint has not been documented. The ventral surface is marked by a groove in a lateral direction. It is an output nucleus whose fibres project to thalamic nuclei, such as the ventral anterior nucleus, the ventral lateral nucleus, and the medial dorsal nucleus. Vet-Anatomy to atlas anatomii weterynaryjnej na podstawie obrazowania weterynaryjnego (MRI, TK, zdjęcia rentgenowskie) oraz ilustracji medycznych, opracowanych i stworzonych przez zawodowych specjalistów w dziedzinie anatomii i obrazowania weterynaryjnego. The ventral horn of the spinal cord is one of the grey longitudinal columns found within the spinal cord. The suboccipital approach alone revealed only a portion of the ventral clivus in the absence of brainstem retraction. It contains the cell bodies of the lower motor neurons which have axons leaving via the ventral spinal roots on their way to innervate muscle fibers.

Supraspinatus Infraspinatus Teres major deltoideus Triceps brachii long head Wire segments were placed on identified ventral plexus nerves and radiographic imaging obtained in multiple planes. The objective of this study was to determine whether ventral innervation to the lateral C1-C2 joint exists, and to describe its relational anatomy. These relay information to the primary somatosensory cortex (Brodmann 3,1,2) by way of the posterior limb of the internal capsule then through the corona radiate (projection fibers).
