REM sleep is associated with . a) temporary skeletal muscle inhibition except for ocular muscles and diaphragm b) decreased vital signs, such as heart rate and blood pressure c) decreased oxygen use, especially in the cerebral cortex d) decreased activity of the brain, especially the cerebral cortex

A.-this is muscular paralysis peculiar to REM sleep. it is needed to restrict muscular movement during dreaming.

Explanation:

All the option listed except A do not take place in Rapid Eye Movements. Generally during sleep, the brain moves through 5 stages of sleep cycle.The REM is one of the stages where the eye moves rapidly in different directions.

It usually begins with the first 90 mins after falling asleep. It is the stage of  dreams,and made up of 50% of infants sleeping cycle. it also consolidate memory formation, mood, and learning.

Generally, the brain is active as one is awake during this stage, thus constant oxygen supply to sustain the brain functions at the cerebral cortex is ensured.  Therefore breathing is rapid and increased. Vital signs increased, blood pressure and heart rate increases as breathing also increases.

A. Temporary skeletal muscle inhibition except for ocular muscle and diaphragm.

Explanation:

The brain moves through five different stages during sleep and one of these stages is the rapid eye movement (REM) sleep. In this stage, several changes takes place in the body and brain. These changes includes;

1. eyes moving rapidly in various directions.

2. Fast and irregular breathing which involves increase in heart rate.

3. The body temperature experience changes.

4. Increase in blood pressure

5. Increase in oxygen consumption by the brain.

During REM sleep, the brain gives signal to the spinal cord to cease movement of the hands and legs.

explanation:

carbon can form so many different compounds not just with oxygen

wait any answer choices plz
