Which of these transports materials in both directions.a. Slow axonal transport
b. Fast axonal transport

Answers

Answer 1
Answer:

Answer: Fast axonal transport

Explanation:

Axonal transport can be defined as the cellular process which controls the movement of mitochondria, proteins, synaptic vesicles, lipids and other parts from and to neuron's cell body through the cytoplasm of its axon.

This is done because some of the neurons are meters long and cannot transport the products from the nucleus to the axon by the process of diffusion so axonal transport is required in this case.

In case of fast axonal transport the movement of the substances takes place in both the directions that is from the axon to nucleus and from the nucleus to axon (retrograde and anterograde)

Shortly thereafter, radiolabeling and histochemical studies demonstrated that faster rates of transport occur [5]. Unlike slow transport, the faster components move material bidirectionally, toward and away from the cell body. Both endogenous proteins and exogenously applied labels were detected moving at fast transport rates. These findings expanded the concept of axonal transport: materials move in both anterograde and retrograde directions and rates vary by as much as three orders of magnitude

A patients pulse oximetry reading is 92%. What is the bestmethod of oxygen administration for this patient?

Answers

Answer:

A low flow oxygen supply

Explanation:

92% is the threshold for hypoxia, meaning that below 92% a person may need Oxygen supply. Depending of each patient's level of saturation, there are different types of devices and pressures, the lower the Oxygen concentration the more the pressure needed, for 92% a patient may require a low pressure system, such as nasal cannula for supply from 24 to 40% of Oxygen concentration. The second option is a face mask, which provides  between 28% and 50%.

The signs and symptoms of Cushing's syndrome result from hypersecretion of ____________

Answers

Answer:

Adrenocorticotropin hormone.

Explanation:

Adrenocorticotropin is a peptide hormone that are mainly released during the stress response of the body. This hormone is released by the anterior pituitary lobe of the brain.

The hypersecretion of adrenocorticotropin hormone can cause the sign's and symptoms of Cushing's syndrome. Cushing's syndrome is the pituitary tumor of the adrenocorticotropin hormone.

Thus, the answer is adrenocorticotropin hormone.

Vaccines are effective because the body "remembers" the exposure to the vaccine's component, and can react swiftly to attack and destroy these components the next time they are encountered naturally in the environment. This occurs becauselymphocytes called "B cells" are activated by certain antigens, and, when combined with a chemical signal from T cells, divide rapidly to form two groups of many identical cells (clones). One group forms the active disease-fighting army of plasma cells, and secrete antibodies into the blood. The second group remains stored in lymph nodes, ready to develop rapidly into more plasma cells at the next exposure to the same antigen. What are these warrior cells, waiting in reserve in the lymph nodes, called?a. cytotoxic cellsb. memory cellsc. macrophagesd. antibodies
