Question | Answer |
---|---|
Afferent Neurons | sensory neurons that link sensory receptors with the central nervous system and transmit sensory information |
Autonomic Nervous System | a division of the peripheral nervous system composed of nerves that connect the central nervous system to the glands, heart, and smooth muscles |
Cranial Nerves | 12 pairs of nerves that transmit information to and from the sensory organs of the face & the muscles of the face, neck, & upper shoulders |
Dermatome | a cutaneous (skin) section supplied by a single spinal nerve |
Efferent Nerves | motor nerves that link the central nervous system to the effectors outside it and transmit motor impulses |
Free Nerve Endings | snesory receptors that detect itch and tickle sensations |
Mechanical Receptors | sensory receptors that detect changes in pressure, movement, temperature, or other mechanical forces |
Mixed Nerves | nerves that contain sensory and motor axons |
Myasthenia Gravis | a disease that usually affects muscles in the face, lips, tongue, neck and throat |
Myotome | a skeletal muscle or group of skeletal muscles that receives motor axons from a particular spinal nerve |
Nerve | a bundle of axons, dendrites or both |
Nociceptors | sensory receptors that detect painful or intense stimuli |
Parasympathetic Nervous System | the energy conservation & restorative system; Relaxed Response |
Peripheral Nervous System | system of somatic & autonomic neurons outside the central nervous system |
Plexus | a network of interwining nerves that innervates a particular region of the body |
Polio | a virus infection; 1st of the intestines and then of the anterior horn cells of spinal cord |
Proprioceptors | sensory receptors that provide the body with information about position, movement, muscle tension, joint activity, & equilibrium |
Reflex | an automatic, involuntary response to a stimuli |
Somatic Nervous System | a system of nerves that keeps the body in balance with its external environment by transmitting impulses among the central nervous system, skeletal muscles, and skin |
Spinal Nerves | 31 pairs of mixed nerves |
Sympathetic Nervous System | part of the autonomic nervous system, Fight or Flight Response |
Thermal Receptors | sensory receptor sthat detect changes in temperature |
