Answer:
The blood volume of an average-sized adult human is approximately:
<em>b) 4-6 liters</em>
Explanation:
Blood volume is the total amount of fluids present in the circulatory system of a person. The normal blood volume in a person can variate according to the person's hydration, size, weight, and amount of blood components (blood cells, platelets, and plasma).
Answer:
When the forearm is extended at the elbow joint, the <u>triceps brachii</u> muscle acts as the prime mover.
Explanation:
Triceps brachii -
Triceps brachii is one of the largest muscle which is presents on the back of the upper limbs of many vertebrates.
The origin of the muscle is Infraglenoid tubercle of scapula.
And
The insertion of the muscle is Posterior olecranon process of ulna.
Actions of Triceps Brachii Long Head are extending the forearm at elbow and extends the arm at the shoulder.
Hence ,
When the forearm is extended at the elbow joint, the <u>triceps brachii</u> muscle acts as the prime mover.
Emergency medications that should be readily available when administering any drug should include epinephrine, diphenhydramine, dopamine and steroids.
<h3>How is dopamine released?</h3>
- Dopamine plays a key role in the brain's reward system by assisting us in experiencing pleasure.
- Dopamine release, sometimes known as a "dopamine rush," can be triggered by sex, shopping, or even the scent of cookies baking in the oven.
- This dopamine-producing neurotransmitter also plays a role in reinforcing.
- A sort of neurotransmitter and hormone is dopamine.
- It affects a variety of vital bodily processes, such as mobility, memory, rewarding pleasure, and motivation.
- Dopamine levels are linked to a number of neurological and mental health conditions.
- Depression, restless legs syndrome, and Parkinson's disease have all been related to low levels of dopamine. Dopamine deficiency can cause a variety of symptoms, including fatigue, moodiness, and lack of motivation.

Answer:
The correct answer will be:
1. Acetylcholine binds to receptors on the motor end plate
2. Chemically-regulated ion channels open, causing depolarization
3 End plate potentials trigger action potential(s).
4. Transverse tubules convey potentials into the interior of the cell
5. Ca++ is released from the sarcoplasmic reticulum
6. Ca++ binds to troponin, pulling on tropomyosin
7. Binding sites on actin are uncovered, allowing myosin to bind and carry out power strokes
8. Force increases.
9. Ca++ is pumped (re-sequestered) into the sarcoplasmic reticulum
10. Force decreases.
Explanation:
The muscle contraction is a highly controlled mechanism which begins at the neuromuscular junction with the release of the acetylcholine neurotransmitter. This neurotransmitter causes the depolarization of the membrane by binding to the receptors of the motor end plate which generates an action potential. This action potential is transmitted via T-tubules from sarcolemma to the sarcoplasmic reticulum.
The sarcoplasmic reticulum releases calcium ions which binds to the troponin protein. This troponin removes the protein tropomyosin from the actin causing the rotation of the tropomyosin exposing the binding sites for myosin. The myosin binds to the actin using energy from the ATP which pulls the actin causing contraction. Another ATP binds the myosin head which weakens the bond between myosin and actin which releases the myosin which decreases the force between them decreases and the muscles relax.
Answer: 36° celsius
Explanation: I live in the states and 36°f is about 2° celsius (assuming that’s your country’s preferred unit of measuring temperature), which is very chilly! 36 celsius for sure.
