Answer:
Gametes
Explanation:
Gametes consist of sperm cells and egg cells...
T-Tubule -Invaginations of the sarcolemma penetrating deep into the interior of the muscle cell.
Synaptic Cleft -the space between the axon terminal and the motor end plate.
Axon Terminal -the swollen distal end of the motor neuron axon.
Sarcolemma -the muscle cell membrane.
Synaptic Vesicles -structures within the axon terminal that contain the neurotransmitter acetylcholine (ACh).
Terminal Cisternae & Sarcoplasmic Reticulum (SR) -structures within skeletal muscle cells that serve as reservoirs of calcium ions.
Motor End Plate -a folded region of the sarcolemma at the neuromuscular junction.
The <u>adrenal gland</u> releases a torrent of hormones, such as epinephrine and norepinephrine as the fight or flight response when a person is stressed or scared.
<h3>What are adrenal glands?</h3>
The adrenal glands are two small organs responsible for secreting hormones such as cortisol, adrenaline or noradrenaline into the bloodstream.
<h3>Characteristics of adrenal glands</h3>
- They are responsible for producing hormones that help regulate metabolism, the immune system, blood pressure, the response to stress and other essential functions.
- The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which initiate the fight or flight response.
Therefore, we can conclude that the adrenal glands release certain hormones in response to stress, some of which are vital for survival.
