Action potential Axsen terminal dendrite neurotransmitter receptors synapse vesicles and calcium ions are the answer
She should try being active by walking around doing chores around her room or something as simple as taking out the trash. body movement is very good no matter how little you’re doing it unless it’s for like 1 second lol
Answer:
The best answer to your question: Which type of neuroglia would play a role in controlling glutamate levels in the chemical environment, would be: Astrocytes.
Explanation:
From among the neuroglia, or support cells in the brain, whose purpose is to aid neurons in their different functions, astrocytes are not just one of the most numerous, but also one of the most vital for neuronal support. Amongst one of their most central functions is to help in the control of neurotransmitter emition and retention in the synaptic cleft, between two communicating neurons, and therefore, helps regulate the responses from post-synaptic, and pre-synaptic neurons. It is also responsible for clearing up the presence of ions in the extracellular space, and producing ATP, which regulates the amount of neurotransmitters that are released, and taken, by pre-synaptic, and post-synaptic neurons.
In ALS (Amyotrophic Lateral Sclerosis) the issue with glutamate, a neurotransmitter that excites post-synaptic neurons into releasing excess amounts of calcium, is that this hyper-excitatory response leads neurons, particularly motor neurons, to die, and this is what causes ALS. It has been found through research that astrocytes have to do in this process, but it is not clear yet whether there is a failure in their control system, as ALS is still a condition that is very much under study and still without a cure.
Answer:
Carina.
Explanation:
Larynx is also known as voice box. This organ is involved in food aspiration and produce sound. Larynx manipulates the pitch and voice of an individual.
The main parts of larynx are cricoid cartilage, thyroid cartilage and arytenoid cartilage. The carina is a part of trachea, not the larynx.
Thus, the correct answer is option (b).
Answer:
b. epididymis/vas deferens/ejaculatory duct/urethra
Explanation:
The male reproductive organs are those which produce sperm and transport them during coitus.
the correct order for the structures sperm pass through as they travel toward the penis:
- Epididymis is the structure where sperm matures and stored till ejaculation.
- Vas Deferens a long tube which conducts sperm from the testes to the ejaculatory duct.
- Ejaculatory duct is a duct which is formed by the union of the vas deferens with the duct of the seminal vesicle. It releases sperm into the urethra.
- Urethra is a canal which conducts semen to the outside of the body via the penis.
