Compare the reaction times for voluntary versus involuntary activation of the quadriceps muscle.

Answers

Answer 1

Voluntary activation of the quadriceps muscle involves the conscious activation of the muscle using a conscious thought.

What is muscle?

Muscle is a type of tissue found in the body that is made up of cells that can contract and relax. Muscles enable movement of the body, enable breathing, and help to maintain posture. Muscles are made up of proteins, and are found in the walls of blood vessels, the skin, and the digestive and urinary tracts.

This process generally takes a fraction of a second and is much faster than the reaction time for involuntary activation. Involuntary activation of the quadriceps muscle involves the reflexive activation of the muscle without conscious thought. This process usually takes a few hundred milliseconds longer than voluntary activation.

Which neurologic drugs have an effect on GABA?

A. clonazepam and lorazepam

B. zolpidem and amitriptyline

C. temazepam and pregabalin

Answers

B. Zolpidem and Amitriptyline, zolpidem is used to treat insomnia so it has an effect on the GABA receptors. Amitriptyline is used to treat anxiety, depression, and other mood disorders; therefore it also has an effect of the GABA receptors.

Answer: Option A, clonazepam and lorazepam, have an effect on GABA. They are both benzodiazepines that enhance the activity of GABA, an inhibitory neurotransmitter in the brain, which leads to sedative and anxiolytic effects. Option B, zolpidem and amitriptyline, are not primarily used for their effect on GABA. Option C, temazepam and pregabalin, have some effect on GABA, but not as significant as clonazepam and lorazepam.
