Answer:
Overweight and obesity are defined as abnormal or excessive fat
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: social studies, social science.
Explanation:
Answer:
The correct option is : a. The phrenic nerve from the cervical plexus
Explanation:
The diaphragm is a thin skeletal muscle which separates the thoracic cavity and the abdominal cavity.
The phrenic nerve is a nerve present in the thoracic region, that passes down between the heart and the lung and reaches the diaphragm.
The phrenic nerve innervates the diaphragm from the C3–C5 of cervical plexus.
Answer:
Experimental Research or Observational trial Reasearch ,
Explanation:
Hard to tell because its not really diving much description and theres about 12 types of research procedures , but those are some of the MOST common research procedures it would 9/10 most likely be.
Hope that helped :D!!!
