Group of answer choices Muscle spindle sensory afferents project to interneurons and lower motor neurons Pain receptor afferent only project to motor neurons Golgi tendon reflex causes contraction of the activating muscle The stretch reflex is a protective circuit that prevents muscle damage None of the above are true

a channel can be gated mechanically, voltage or by a ligand. When you hear a sound all three of these type channels are being utilized. Explain generally where/how each of these channels are being utilized starting from hearing the sound, through travelling down a nerve to transmission to another nerve.

Put the items in the correct order. Sensory neuron is activated. Processing of the sensory signals occurs inside CNS. Motor neuron carries impulse to peripheral effector. Check Answer 1 1

26) You are being approached by a bear in the woods. Unlike what you may have heard, you do not want to play dead (bears eat dead things) and you do not want to run or climb a tree because the bear is faster than you. You need to make the bear think you are a threat by looking big and speaking to it. a) Which part of the nervous system has been activated, specifically. b) Name two organs/tissues that will be activated/ receive blood. c) Name two organs/tissue that will be deactivated/ have blood diverted.

What do you mean by efferent nerves? Name the parts of body where they are present.
