Answer:
True
Explanation:
Sensory neurons are the neurons present in the nerves which can convert the external stimuli into an electrical signal and can transmit the signals from the organs to the central nervous system.
The structure of sensory neuron in pseudounipolar that is at one end it has dendrites and another end transmits the signals to the CNS.
The cell bodies (nucleus) of these sensory neurons are located in the structures called ganglia located outside the CNS.
Thus, True is the correct answer.
Answer:
The correct answer will be option-a synergist
Explanation:
In the musculoskeletal system, the muscles to produce a movement work in group or pairs like hamstrings and quadriceps or biceps or triceps. The muscles which work is known as an agonist or prime mover.
The muscle which helps prime mover by moving in the same direction and at the same time is known as synergists. The synergists produce a similar motion as the prime mover and also stabilizes the joints which hold the position for smooth movement of agonist.
Thus, synergist is the correct answer.
T
The answer you are looking for is C.
1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
