Soft palate
The soft palate is composed of muscle and connective tissue, which give it both mobility and support. This palate is very flexible. When elevated for swallowing and sucking, it completely blocks and separates the nasal cavity and nasal portion of the pharynx from the mouth and the oral part of the pharynx.
Answer:
The correct answer is B.
Explanation:
During the follicular phase (first half of female cycle), follicles in the ovary begin developing under the<u> influence of </u><u>FSH.</u> <em>The follicle that acquires more FSH receptors will become </em><em>dominant</em> and will produce more estrogen and inhibin hormone than the others. Inhibin will reduce FSH level and as a result the other follicles will fail to keep growing. At this stage the dominant follicle will become FSH independent.
Estrogen produced by the dominant follicle will stimulate LH secretion. After approximately 24-36 hours from when LH reaches its peak level, the dominant follicle releases an ovocyte. <em>This event is called ovulation.</em>
Answer: Fibrous pericardium and Serous Pericardium
Explanation:
The pericardium can be defined as the fibroserous sac( double layered) which covers the whole heart. The gap between two layers of serous pericardium is filled with serous fluid. This fluid protects the heart from external shocks.
Fibrous pericardium
This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.
Serous pericardium
This layer provides lubrication to the heart by resisting the friction which occurs during the various type of heart function.
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.
