Answer:
A. Motor Neuron
Explanation:
Motor neurons which can also be referred to as the lower/alpha motor neurons, furnishes skeletal muscle and causes the muscle to contract, this thereafter generates movement. <em>Motor neurons releases neurotransmitter acetylcholine at the neuromuscular junction that stimulates muscle cells to contract. </em>
At the point when the acetylcholine ties to acetylcholine receptors on the muscle fiber, an activity potential is proliferated along the muscle fiber in the two ways. The activity potential triggers the contraction of the muscle. On the off chance that the end of the muscle are fixed, keeping the muscle at a similar length, at that point the compression results on an expanded power on the backings which is referred to as<em> isometric contraction</em>. On the off chance that the muscle abbreviates against no obstruction, the constriction brings about steady power which is referred to as <em>isotonic contraction</em>. The engine neurons that control appendage and body developments are situated in the front horn of the spinal line, and the engine neurons that control head and facial developments are situated in the engine cores of the brainstem. Despite the fact that the engine framework is made out of various kinds of neurons dispersed all through the CNS, the engine neuron is the main manner by which the engine framework can speak with the muscles.
Ultimately, every movements will rely on the activity of the alpha motor neurons.
B. all eukaryotic cells
hoped this helped!
Answer:
The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.
Explanation:
The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.
Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.
Option D
Research on the physiological states accompanying specific emotions indicates that each emotion has a unique pattern of sympathetic nervous system activity
<u>Explanation:</u>
Emotions are usually characterized by thinking and sense elements that point our consciousness and control our response. By the sympathetic portion of the autonomic nervous system, sensitive events followed by excitement feel and actions of the physical acknowledgments are produced.
Emotions enhance especially prominent in leading options when the dilemmas among various complicated and contradictory options confer us with a great measure of contingency and vagueness, proffering a comprehensive cognitive study challenging. Urges are powers that control the action. The cognitive evaluation also enables us to encounter a kind of trivial sensations.
