Select the correct answer from each drop-down menu.

Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.

Answer:

synapse

neurotransmitter

Explanation:

Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.

The neuron receives signals through dendrites and two neurons  communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.

Hence, the correct answers are synapse and neurotransmitter.

The nursing instructor informs the students that which anatomical structure controls the elimination of urine from the body?
Tomtit [17]

The Urinary bladder controls the elimination of urine from the body.

  • The lower abdomen contains this triangle-shaped, hollow organ. Ligaments that are connected to the pelvic bones and other organs hold it in place.
  • When storing pee, the bladder's walls relax and expand; when emptying urine through the urethra, they contract and flatten.
  • The typical healthy adult bladder has a two to five-hour storage capacity of up to two cups of urine.

Three parts of bladder allow urine to be discharged:

  • A pair of sphincter muscles. By tightly shutting around the bladder opening like a rubber band, these circular muscles assist prevent urine leakage.
  • In the bladder's nerves. When it's time to urinate or empty the bladder, the nerves let the person know.
  • Urethra. Urine can travel through this tube and leave the body. Urine leaks from the bladder as a result of the brain's tightening signal to the bladder muscles.
