Central nervous system-the complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord.
Peripheral nervous system-the nervous system outside the brain and spinal cord.
Somatic nervous system-is the part of the peripheral nervous system associated with skeletal muscle voluntary control of body movements. The SoNS consists of afferent nerves or sensory nerves, and efferent nerves or motor nerves.
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.
Sensory neurons- a nerve cell that conducts impulses from a sense organ to the central nervous system.
Interneuron-a neuron that transmits impulses between other neurons, especially as part of a reflex arc.
Motor neuron-a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland.
Neuromuscular junction-is a synapse between a motor neuron and skeletal muscle. This lesson describes the events of synaptic transmission leading to contraction of skeletal muscle. Myasthenia gravis is described as a neuromuscular disease.
Acetylcholine-a compound that occurs throughout the nervous system, in which it functions as a neurotransmitter.
a hormone that is released by the adrenal medulla and by the sympathetic nerves and functions as a neurotransmitter. It is also used as a drug to raise blood pressure and another term for adrenaline.
Synapse-a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
White Matter the paler tissue of the brain and spinal cord, consisting mainly of nerve fibers with their myelin sheaths.
Gray matter-
Cerebral Cortex the outer layer of the cerebrum (the cerebral cortex ), composed of folded gray matter and playing an important role in consciousness.
Frontal lobe: motor strip location, impulsivity, short term memory, emotion, voluntary movement, social functioning, creativity, expressive language. Parietal lobe: sensory strip location, perception, touch(pain & temperature), ability to draw, reading and writing, calculations. Occipital lobe: perception, vision Temporal lobe: hearing, long term memory, verbal and written recognition memory, receptive memory, music, initiation of verbal.
Limbic System a complex system of nerves and networks in the brain, involving several areas near the edge of the cortex concerned with instinct and mood. It controls the basic emotions (fear, pleasure, anger) and drives (hunger, sex, dominance, care of offspring).
