What is a receptor? Provide an explanation then give one example of where a receptor is found, explaining its role is in monitoring homeostasis.

Answer these 2 questions please.

Extracellular recordings create a distinct action potential. Choose the option that best describes the trace recording after stimulation.    1.The voltage trace becomes increasingly positive because the extracellular space becomes less negative 2.The voltage trace becomes increasingly positive because the extracellular space becomes less positive 3.The voltage trace becomes increasingly negative because the extracellular space becomes less positive 4.The voltage trace becomes increasingly negative because the extracellular space becomes more positive

Place the following events in chronological order from 1-8: Nat enters the cell, and depolarization occurs to approximately +30 mV. The voltage across the cell membrane is -70 mV, the resting membrane potential. Upon reaching the peak of the action potential, the VG Nat channels are inactivated by the closing of their inactivation gate and the activation gate of each VG K channel opens. VG K channels close by the closing of their activation gate, and the resting membrane potential is gradually restored. An excitatory post-synaptic potential depolarizes the membrane to threshold and the activation gate of VG Nat channels open. Upon returning to the resting membrane potential, VG Na channels are reset by opening of the inactivation gate and the closing of the activation gate. VG K+ channels are slow to close, resulting in an excess of K* efflux and hyperpolarization. Depolarization occurs as K+ flows out of the cell.

Please provide approximately one paragraph b them discuss the following two questions about neurons. Question 1: Is there a relationship between the morphology (shape) and function of a neuron? Question 2: Many neurons differ in appearance due to the number of dendrites they have. What would be the advantage to a neuron to have multiple dendrites?

the following structure will carry efferent impulses from central nervous system to skeletal muscles to make them contract: select one: a b c d e f g h
