Answer:
A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is usually compact. The axon and dendrites are filaments that extrude from it. Dendrites typically branch profusely and extend a few hundred micrometers from the soma. The axon leaves the soma at a swelling called the axon hillock (<em><u>the axon hillock also has the greatest density of voltage-dependent sodium channels. This makes it the most easily excited part of the neuron and the spike initiation zone for the axon</u></em>) and it branches but usually maintains a constant diameter. At the farthest tip of the axon's branches are axon terminals, where the neuron can transmit a signal across the synapse to another cell.
<em>In general, dendrites receive the electrical signal from other neurons, and this signal is transmitted over long distances from the axon.</em>
Like all animal cells, the cell body of every neuron is enclosed by a plasma membrane, a bilayer of lipid molecules with many types of protein structures embedded in it. A lipid bilayer is a powerful electrical insulator, but in neurons, many of the protein structures embedded in the membrane are electrically active. These include ion channels that permit electrically charged ions to flow across the membrane and ion pumps that chemically transport ions from one side of the membrane to the other to generate the action potential that generates the electrical signal. They also have a highly developed synthetic apparatus for the production of neurotransmitters
Monkeys, birds, frogs, snakes, rodents, lizards, and insects are some animals, and mosses, ferns, and orchids are some plants found in the Tropical Rainforest.
Answer:
Gliding
Explanation:
occurs when two bones slide across one another, such as in the intercarpal joints.
Answer:
d. Measure thyroid-stimulating hormone level
Explanation:
The most suitable next step in management of this patient is to measure a thyroid stimulating hormone, or thyrotropin level.
This patient's apparent treatment refractory dyslipidemia is most likely contributed by undiagnosed thyroid disease. Despite sticking to the treatment with atorvastatin, his LDL AND total cholesterol are raised.
Additionally, there are some clinical signals that give an idea about the diagnosis of hypothyroidism especially fatigue and constipation.
Hypothyroidism is concerned with and is a very common secondary cause of dyslipidemia and thyrotropin level measures are indicated.
Hyperlipidemia may show better results to thyroid stimulating hormone.
Hence option D is the right answer.
In aplastic anemia, then lab result will be decreased in all blood component( white blood cells, red blood cells, and thrombocyte).
Aplastic anemia is caused by the bone marrow failure. Bone marrow is the place that produces blood cells, so the decrease wouldn't be in the red blood cell only, but in other blood cells too. There shouldn't be any iron deficiency or decreases in the mean corpuscular volume
