Lateral ventricle (Ventriculus lateralis) The lateral ventricles are the largest in the series of four interconnecting fluid-filled cavities within the brain.These cavities and their interconnecting channels, constitute the cerebral ventricular system.. The lateral division contains most of the unmyelinated and small myelinated axons carrying pain and temperature information to be terminated in the Rexed laminae I, II, and IV of the gray matter.

Upper Arm (Deltoid Muscle) Your deltoid muscle is located in your upper arm, just below your shoulder. Another word for ventral. Anterior and Posterior. Dorsal root fibers are the axons originated from the primary sensory dorsal root ganglion cells, Bifurcate into ascending and branches that enters several segments above and below their own segment. The biceps brachii are on the other side of the foream, and lie underneath the cat’s shoulder muscle, the clavobrachialis (in humans, we usually refer to this muscle as the deltoid, due to its triangular shape). It means "not coded here". Fetal Pig Practice Quizzes on Quizlet. From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.
