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:
The ovaries would be correct :)
Answer:
The answer is A: Skeletal muscle
Explanation:
In the sympathetic nervous system (SNS) the effectors can be of two types:
1. Motor effectors = are the skeletal muscles and are responsible for fulfilling the motor orders of the nervous system.
2. Secretory effectors = are the exocrine glands that when stimulated produce a hormonal secretion in the corresponding organ.
Answer:
Set a reasonable goal and manage expectations.
Explanation:
"I want to change my diet so I can be healthier within the next three months" is an extremely broad goal. If we want to make this a decisive goal we can start by asking two questions, how and why.
How:
I want to eat healthier food in proper moderation by meal prepping my lunches for the week and creating a meal plan for dinner and breakfast so that I eat healthier foods.
(This states briefly what you want to do and also a means to achieve that goal. simply stating you want to do something (especially a very broad thing) in retrospect means very little)
Why:
I want to lose 15 pounds in the next 3 months so I can feel better about how I look.
(15 pounds in the next three months is a tough goal for a lot of people however, simply stating you want to be healthier is not a goal that's easy to track. Set a trackable goal such as losing X amount of weight or limiting carbs or saturated fats per day)
New Statement:
I am going to start planning my meals and meal prepping every week so that I can reach my goal weight in 3 months.
