Nervous System Flashcards
nervous system
the network of nerve cells and fibers that transmits nerve impulses between parts of the body.
sensory input
stimuli that is perceived by our senses like smell, sight, touch, taste, and hearing
integration
the action or process of integrating
central nervous system
the complex of nerve tissues that controls the activities of the body.
peripheral nervous system
the nervous system outside the brain and spinal cord.
somatic nervous system
the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements
autonomic nervous system
the part of the nervous system responsible for control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes.
neuroglia
non-neuronal cells that maintain homeostasis, form myelin, and provide support and protection for neurons in the central and peripheral nervous systems.
astrocytes
are characteristic star-shaped glial cells in the brain and spinal cord.
microglia
glial cells derived from mesoderm that function as macrophages (scavengers) in the central nervous system and form part of the reticuloendothelial system.
ependymal cells
These cells line the CSF-filled ventricles in the brain and the central canal of the spinal cord.
oligodendrocytes
the myelinating cells of the central nervous system
Schwann cells
any of the cells in the peripheral nervous system that produce the myelin sheath around neuronal axons.
satellite cells
are precursors to skeletal muscle cells, able to give rise to satellite cells or differentiated skeletal muscle cells
neurons
a specialized cell transmitting nerve impulses; a nerve cell.
