In the micturition reflex, high volumes of urine stretch the wall of the bladder. This excites interneurons in the sacral region of the spinal cord. These interneurons cause pelvic splanchnic motor neurons to fire. The bladder contracts and pushes urine against the opening to the urethra. Check the boxes that identify the type(s) of reflex represented by the micturition  reflex. Check all that apply (i.e., there could be more than one right answer).

A familiar type of monosynaptic reflex that uses muscle spindle mechanoreceptors to monitor the length of skeletal muscle fibers and causes muscle contraction in response is called the…

The increase in muscle tension that occurs with an increase in the intensity (voltage) of a stimulus is called…

Put these general events involved in synaptic transmission in chronological order.

Is the statement below True or False? Tetany occurs when stimulation of a muscle fiber is so frequent that there is no relaxation..

Compare the values below. Which is greater, or are the two values equal? A. Motor unit size in the muscles of the hand B. Motor unit size in gluteus maximus

In adults, the spinal cord is not the same length as the vertebral canal, and most of the lumbar part of the spinal cord is within…

Is the statement below True or False? Tetany occurs when stimulation of a muscle fiber is so frequent that there is no relaxation..

The image above represents an experimental setup where a motor neuron and a muscle cell it innervates are each fitted with a stimulating electrode. For each of the situations below, indicate whether the muscle cell would produce a normal twitch, an extra-long twitch, or no twitch.
