Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.
Glia, also called glial cells (gliocytes) or neuroglia, are non-neuronal cells in the central nervous system (the brain and the spinal cord) and in the peripheral nervous system that do not produce electrical impulses. The neuroglia make up more than one half the volume of neural tissue in the human body. [1]
Chloroplasts in leaf cells of the moss Mnium stellare. Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
Schwann cells or neurolemmocytes (named after German physiologist Theodor Schwann) are the principal glia of the peripheral nervous system (PNS). Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ensheathing cells, enteric glia and glia that reside at sensory nerve endings, such as the Pacinian corpuscle.
Satellite glial cells, formerly called amphicytes, [1] are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system.Thus, they are found in sensory, sympathetic, and parasympathetic ganglia.
FBI Director Christopher Wray’s resignation announcement was the latest, and inevitable, step in the accumulation of massive and unusual power around President-elect Donald Trump.
Instead, the entire subarachnoid space is sealed towards the nervous tissue by the glia limitans superficialis. [3] These two parts of the glia limitans are continuous; however, convention dictates that the part that covers the surface of the brain is referred to as the superficialis, and the part that encloses the blood vessels within the ...
Rep. Nancy Mace unveiled legislation Thursday aimed at protecting women and children from registered sex offenders in emergency shelters during the fallout from natural disasters.
