Nervous System |
Is the master control and communication system of the body. |
|
Sensory Input Integration Motor Output |
3 Overlapping Functions of Nervous System. |
|
Central Nervous System Peripheral Nervous System |
2 Types of Nervous System |
|
Central Nervous System |
It is consist of the brain and the spinal cord. Interpret incoming sensory information. |
|
Peripheral Nervous System |
It is consist of the cranial and spinal nerves. |
|
Spinal Nerves |
Carry impulses to and from the spinal cord. |
|
Cranial Nerves |
Carry impulses to and from the brain. |
|
Sensory Division (afferent)Motor Division (efferent) |
Functional Classification of PNS Structure |
|
Sensory Division |
Consist of nerves that convey impulses to the central nervous system from sensory receptors located in various parts of the body. |
|
Motor Division |
Carries impulses from the CNS to effector organs, the muscles and the glands. |
|
Somatic Nervous System |
Also known as the Voluntary Nervous system. Allows us to consciously or voluntarily control our skeletal muscles. |
|
Autonomic Nervous System |
Also know as the involuntary nervous system. Regulates involuntary events such as the activity of smooth muscle, cardiac muscle and glands. |
|
Neuroglia |
Nerve glue, also known as glial cells or glia. |
|
Astrocytes |
Abundant star-shaped cells that account for nearly half of neural tissue. |
|
Microglia |
Spiderlike phagocytes that monitor the health of nearby neurons and dispose of debris, such as dead brain cells and bacteria. |
|
Ependymal Cells |
Neuroglia that line the central cavities of the brain and the spinal cord. |
|
Oligodendrocytes |
Neuroglia that wrap their flat extensions tightly around the nerve fibers. |
|
Myelin Sheaths |
Fatty insulting coverings. Product of oligodendrocytes.. |
|
Gliomas |
Tumors formed by neuroglia |
|
Schwann Cells |
It forms the myelin sheaths around nerve fibers in the PNS. |
|
Satellite Cells |
It acts as the protective, cushioning cells for peripheral neuron cell bodies. |
