Triggering of the muscle action potential occurs after

Biology
1 answer:
vekshin13 years ago
4 0

Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.

An action potential is an electrical signal that travels along the cell membrane as a wave.

This action potential (muscle action potential) drives the contraction of muscle fibers.

When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.

Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.

How to compare directional and disruptive selection?
dangina [55]
 Both of th
 <span>Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to "move" in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white, pink, or red. Pink flowers may be the average phenotype, but if we start to remove red flowers from the population, the "mean" phenotype will be shifted toward white flowers. 
In disruptive selection, the average phenotype is selected against. This produces a "two-humped" bell-type curve, and the greater distribution is split between the two phenotype extremes. If we have the same type of incomplete dominance as mentioned in the previous paragraph, assume that the pink flowers are selected against. This means that the two "humps" shown in the distribution will be centered around the red and white phenotypes</span>

How do phagocytes protect the body
Olin [163]

1) pathogen enters body and releases chemoattractants

2) a phagocyte/macrophage is attracted by these chemicals

3) the phagocyte engulfs the pathogen using its pseudopodia

4) the membranes of both organisms fuse forming a phagosome

5) lysosomers in the phogocyte fuse with the phagosome, forming a phagolysosome

6) these enzymes digest the pahogen (hydrolyse the bonds)

7) the antigens of the pathogen are placed on the surface of the phagocyte making an APC (antigen presenting cell)
