The cells have their bodies in the cerebral cortex, and the axons form the bulk of the pyramidal tracts. [4] The nerve axons travel from the cortex through the posterior limb of internal capsule, through the cerebral peduncle and into the brainstem and anterior medulla oblongata. Here they form two prominences called the medulla oblongatary ...
Nereid, or Neptune II, is the third-largest moon of Neptune. It has the most eccentric orbit of all known moons in the Solar System . [ 4 ] It was the second moon of Neptune to be discovered, by Gerard Kuiper in 1949.

These cells might also play a critical role in complex object recognition within the visual processing areas of the cortex. [3] Relative to other species, the larger cell size and complexity of pyramidal neurons, along with certain patterns of cellular organization and function, correlates with the evolution of human cognition. [22]
Subsets of sensory intestinal epithelial cells synapse with nerves, [9] and are known as neuropod cells. [10] Paneth cells produce antimicrobial peptides such as human alpha-defensin. [11] [12] Microfold cells (commonly referred to as M cells) sample antigens from the lumen and deliver them to the lymphoid tissue associated with the mucosa (MALT).
These perisomatic (around the cell body) and basal dendrites project into all cortical layers, but most of their horizontal branches/arbors populate layers V and VI, some reaching down into the white matter. [5] According to one study, Betz cells represent about 10% of the total pyramidal cell population in layer Vb of the human primary motor ...
In humans and other mammals, the caudal cell mass (also tail bud or caudal eminence in humans) is the aggregate of undifferentiated cells at the caudal end on the spine.The caudal end of the spinal cord first begins to form after primary neurulation has taken place, indicating that it develops after the cranial portion of the spinal cord has developed.
