Answer:
The answer to the question: Where does the stimulus occur in order to initiate an AP, would be, B: Dendrites.
Explanation:
When an impulse is to be generated and passed on as an action potential towards a corresponding neuronal cell, and a final affected organ, the neurons need first to be stimulated so that an action potential begins. This stimulus comes as a neurotransmitter released by other neurons near the one that will be stimulated. This neurotransmitter will bind to the receptors on the dendrites of the neuron to be stimulated and immediately this will cause the ion channels, gated and non-gated, to open and close so that an action potential can be initiated. The cell body then initiates the first action potential, and will in turn stimulate the axon to also start their own action potential, which will, like a domino effect, move down to the axon terminals. This process will be followed all along a neuronal circuit.
Answer:pounds (lbs)
Explanation:
Lbs is the is measurement for weight
Answer:
A) bind to receptors in the nucleus of their target cells.
Explanation:
Steroid hormones are synthesized from cholesterol and are lipids, therefore they cannot be transported in the blood dissolved in the plasma. They are associated with transport proteins to travel in blood.
Because they are lipids, they can diffuse through cell membranes, and once inside the target cell they bind to receptors in the cytoplasm or the nucleus and alter gene expression.
Many of the symptoms that make a person suffer during an infection—fever, malaise, headache, rash—result from the activities of the immune system trying to eliminate the infection from the body. In response to infection, your immune system springs into action.
Answer:
tunica intima (inner layer)
Explanation:
Walls of veins is composed of three layers, which are:
- A. Outer layer (tunica adventitia) is of connective tissue with the collagen fibers.
- B. Middle layer (tunica media) is of smooth muscle which are arranged circularly and the elastic fibers.
- <u>C.Inner layer (tunica intima) which consists of specialized simple squamous epithelium which are also known endothelium which lines all the blood vessels and endocardium of heart.</u>
