BSC 181 Lecture Notes - Lecture 1: Epineurium, Peripheral Nervous System, Spinal Nerve
Document Summary
Please note that this review does not cover all of the material discussed in the lecture notes. Exam questions will come from the lecture material, not this review. All of which provide links to the world outside the body based on type of stimulus, location, and structural complexity. Sensory receptors = specialize in response to changes in the environment. Graded potentials trigger nerve impulses: sensation and perception (take place in the brain) Mechanoreceptors: respond to touch, pressure, vibration, and stretch. Chemoreceptors: respond to chemicals taste changes in blood chem. Exteroreceptors: (external) repond to stimuli arising from outside of body. Receptors in skin for touch, pressure, pain, and temp. Interoceptors: (internal/visceroceptors) respond to stimuli in internal viscera and bv. Sensitive to chemical changes, tissue stretch, and temp. Proprioceptors: (movement at joints) respond to stretch in skeletal muscle, tendons, joints, liga(cid:373)e(cid:374)ts. Receptors for general senses temp, pain, muscle sense, touch, pressure, vibration. Receptors for spinal senses (vision, hearing smell, taste)
