What is the correct order of the 5 basic components of a reflex arc?   A. effector, sensory neuron, motor neuron, integration center, receptor   B. integration center, receptor, sensory neuron, motor neuron, effector   C. receptor, sensory neuron, integration center, motor neuron, effector   D. sensory neuron, receptor, integration center, effector, motor neuron

Please help me, idk if my answer is correct and I am trying to use this to study!!

Answer True or False for each of the following: A. a neuronal synapse, facilitation of a post -synaptic response results because of an accumulation of calcium ions from previous pre-synaptic cell action potentials. B. In general, chemical synapses are limited because the signal they produce is “all-or-none” and cannot be significantly modified to reflect a difference in sensory. C. Temporal summation describes the cumulative EPSPs/ IPSPs generated in a post-synaptic cell through more than one synapse.

A synapse with all of these; a postsynaptic dendrite, an astrocyte end foot, and the presynaptic terminal button/bouton is called..... A. synaptic convergence B. engulfment synapse C. tripartite synapse  D. receptor confluence synapse  E. astrocytic engulfment

Plz answer correctly asap

I struggle with my homework. Can you help me?

Subject: Neurophysiology  Batrachotoxin OPENS Na+ channels.  If this is added to a bath solution in a Neuromuscular junction preparation a. What would happen to the nerve resting membrane potential?         b. Do you think that the toxin interacts with activation or inactivation gates?  Why?                                                               c. Na ion influx is massive with Batrachotoxin.  Would you predict a change in nerve cell volume?  Why?

Your hand touches the surface of a hot stove. Without thinking, you immediately pull your hand away. The correct order of the components of the reflex arc that pulls your hand away is: a. sensory receptors → sensory neurons → motor neurons → interneurons → effectors b. effectors → sensory neurons → brain → motor neurons → sensory receptors c. motor neurons → effectors → brain → sensory neurons → interneurons d. sensory receptors → sensory neurons → interneurons → motor neurons → effectors

We're almost there, just one more push, please help me, the end is in sight
