Which of the following neurotransmitters typically has inhibitory effects?
solmaris [256]

The correct answer is: A) GABA

GABA or γ-aminobutyric acid is a type of amino acid that's found in proteins. It is the main inhibitory neurotransmitter in the brain which means that GABA reduces neuronal excitability throughout the nervous system. GABA binds to its receptors that are located on the neuron’s plasma membrane. This binding causes the opening of ion channels that transport chloride ions into the cell or potassium ions out of the cell.

MariettaO [177]

Answer:

the rhythm of heart contractions.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

An electrocardiogram (ECG) provides information about the rhythm of heart contractions.

Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
