ANATOMY 1 Lecture Notes - Lecture 21: Efferent Nerve Fiber, Peripheral Nervous System, Skeletal Muscle
Document Summary
Sensory or afferent neurons carry sensory information into brain and spinal cord through cranial and spinal nerves. Processing of sensory information through analysis and storage => make decision for appropriate response. = neurons that interact w/ other neurons. Axons extend short distances to contact nearby neurons in the brain or spinal cord. Carry info from brain towards spinal cord. Or out of brain/spinal cord to effectors through cranial and spinal nerves. Stimulation of effectors by motor neurons => contraction of. Functional components of peripheral nervous system muscles/secretion of glands. = sensory neurons that convey info to cns from sensory receptors in skin, skeletal muscles, joints. Also from receptors for vision, hearing, equilibrium, taste, smell. Path for the input of this information to cns for integration. Convey info from cns to skeletal muscle only. Output of info from cns to skeletal muscle. Convey info to cns from autonomic sensory receptors. Autonomic sensory receptors located in visceral organs.
