All About Nerve Tissues

Nervous Tissue Functions of Nerve Tissue Allows an organism to feel stimuli in two the internal and international surround. The stimuli atomic descend 18 analyzed and integrated to translate appropriate, coordinated responses in various organs. The afferent or afferent neurons conduct presumption nerve nerve impulses from the sense organs and receptors to the central uneasy system. Internuncial or continuative neurons supply the connection between the afferent and efferent neurons as well as different separate of the central vile system. Efferent or somatic motor neurons transmit the impulse from the central nervous system to a muscle (the effecter organ) which then react to the initial stimulus. involuntary motor or efferent neurons transmit impulses to the involuntary muscles and glands. Neuron It is the structural building block of the nervous system. It gathers and processes informati on from receptors in contact with the external environment and generates appropriate response signals. Networks of neurons help combine twofold sensory(prenominal) signals responsible for complex behaviors like abstract thinking, learning, memory, language, planning, etc. When damaged, they do not regenerate.
