Unlike the somatic nervous system, the autonomic nervous system does not use a terminal synapse to communicate with an effector. Instead, enlargements called en passant synapses or varicosities contain neurotransmitters that are released as the action potential passes along the postganglionic axon. (Note: The diagram includes text boxes for the terms "autonomic," "en passant synapses," and "varicosities," indicating their placement within the explanation. There is also a space for user input with the instruction: "Please type your answer to submit.")

I need help with this flow chart summarizing the divisions of the peripheral nervous system.
Please answer asap and in short
Drag and drop the terms or phrases into the correct spots so they are the matching characteristics for the neurons. You can use some more than once. CHARACTERISTICS FUNCTION DENDRITES CELL BODY AXONS MYELIN long dendrite cell body inside CNS short axon SENSORY NEURON short dendrites cell body outside CNS long axon myelinated axon myelinated dendrite & axon white & grey matter AP away from CNS AP towards CNS AP within CNS INTERNEURON MOTOR NEURON
Which of the following is characteristic of parasympathetic ganglia the ganglia are formed of the cell bodies of general somatic efferent neurons O the ganglia are formed of the cell bodies of preganglionic neurons parasympathetic autonomic ganglia are ALL found within the walls of the effector glands or organs synapses between preganglionic and postganglionic neurons are formed within the autonomic ganglia
If a post synaptic neuron is stimulated to threshold by spatial summation this implies that the post synaptic cell has a lower than normal threshold the postsynaptic cell has many synapses with many presynaptic neurons the post synaptic cell is getting stimulated many times during a short period of time by a single presynaptic neuron the post synaptic cell is slow to repolarize
What is one way that a chemical can alter normal functioning at the synapse? Give me the specifics of what the chemical interacts with in the synapse and what that does.
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.
Neuronal integration refers to the ability of neurons to respond to the combined effect of several EPSPs and IPSPs True False
