Nervous System Concept Map
Nervous Tissue
Neurons
Able to divide; therefore are responsible of neoplasms.
Support,insulate and protect cell
Are amitotic
Release neurotransmitters.
demonstrate irritability and conductivity; thus to these send messages area to area via electrical.
Neuroglia
Major functions of NS
integration - interpretation of sensory information; complex functions
sensory monitors internal & external environment through presence of receptors.
Motor - processed information trough stimulation of effectors.
Major divisions and subdivisions of the nervous system
Central Nervous System
interprets incoming information and issues orders,composed of brain and spinal cord.
Peripheral Nervous System
Nervous system subdivision that is composed of cranial and spinal nerves also added the ganglia. Serves also as communication links that connect all the body parts to (CNS).
Autonomic Nervous System
Subdivision of (PNS) that regulates the activity of heart,glands and smooth muscle also called the involuntary nervous system.
Somatic Nervous System
Subdivision of (PNS) that controls the voluntary movement as the activation of skeletal.
