Explanation:

The neuronal membrane.

Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient. Parts of a neuron are separated into  the

  • dendrites which receive messages from other neurons allowing them to pass and some of the cell body which contains typical cell components like the nucleus,  endoplasmic reticulum and mitochondria.
  • The axon is an insulated (by the myelin sheath) tubular structure which acts as a bridge to price impulses to other neurons these also contain axon hillocks which are junctions between the axon and  cell body
  • Synapses are junctions  where axons connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals.
  • There are several neuron types which include sensory motor and into neurons which bridge the two.

The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.

Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell;  with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential

At synaptic junctions:

  • The action potential travels along the membrane until the synapse where it’s electrical depolarization leads to the opening of channels allowing only sodium ions to enter
  • these flow through a presynaptic membrane until the concentration is built up, activating ion sensitive proteins attached to vesicles containing neurotransmitters
  • this leads to changes in the proteins leading to the fusion with the membrane of the presynaptic cell, so vesicles are open and neurotransmitter is released. The neurotransmitter diffuses across to chemical receptors on the presynaptic cell where they bind temporarily
  • This leads to activation of specific complexes, enabling the transmission of information. Thus, the chemical signal is transferred through this neuron as an electrical impulse

Novocaine, an ester, is a compound that  inhibits sodium channel ion exchange leading to membrane depolarization (charges equilibrium).  It stabilizes the neronal membrane preventing transmission of nerve impulses as a local anesthetic to pain centers in the CNS.

Greeley [361]

Answer:

Pulmonary tuberculosis. It is a disease caused by a resistant acid bacterium and weight loss, persistent chronic cough and night sweats are characteristic of its symptoms. In addition to these discomforts, they will present hemotipsis, that is, the presence of blood in the sputum. The diagnosis is confirmed by the presence of spots in the lungs and positive sputum and culture tests for the presence of AFB (Acid- Fast Bacilli).

Compare and contrast drugs and supplements. Give 2 ways that they are similar and 2 ways they are different.
Sever21 [200]
In the ways drugs and supplements are the same are they both have an effect of the body's nervous system and both are psychoactive substances. In the ways they are different, drugs are often used for overcoming a illness while supplements are not necessary and are optional. Hope I helped!
