Sinusoid (Discontinuous) Capillaries

A unique variety of capillary, sinusoid capillaries are present in the endothelium and have quite big, open holes.

There are sinusoid blood veins in the lymph nodes, the adrenal glands, and even the bone marrow. Some cells do not have tight connections between them; these cells are typically found in the liver and spleen.

These tiny blood arteries, referred to as sinusoids, contain open pores as opposed to the continuous and fenestrated forms of capillaries. Contrary to sinusoid capillaries, which lack a diaphragm and only contain an exposed open pore, fenestrated capillaries have diaphragm-like structures that cover the pores.

The permeability of the capillary is increased by these open pores, and this permeability allows albumin and other small- and medium-sized proteins to enter and leave the bloodstream.

What are Kupffer cells used for?

Kupffer cells, sometimes referred to as stellate macrophages and Kupffer-Browicz cells, are specialized cells found in the liver's sinusoids lumen and are adhering to the endothelial cells that make up the blood channel walls. The majority of tissue-resident macrophages in the body are found in kupffer cells.

How do humans (and other animals) rely on the products of<br> photosynthesis?

baherus [9]

Answer:

Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants. Moreover, the oxygen humans and other animals breathe is the oxygen released during photosynthesis.

How would a mistake in transcribing the DNA message affect your ability to catch the killer?

mel-nik [20]

Answer: When the DNA collected on the crime scene is being analysed in the forensic lab, the results will be inconclusive, because error in DNA transcription, particularly in mRNA encoding leads to inheritable phenotype change by reprogramming the transcriptional network, without changing the DNA. Transcription errors are brief with no long-term consequences. Due to mRNA being short-lived and the erroneous proteins are degraded. A decrease in transcription accuracy triggers cellular identity change.

Explanation: This is called epimutation, a heritable modification that results in the change of gene expression, but not the DNA sequence. Epimutation is not associated with DNA mutation, but is associated with the loss or gain of DNA methylation or other heritable changes of the chromatin.

White matter is found in all of the following locations EXCEPT the ________. a) cerebral cortex b) corpus callosum c) corticospi

Eddi Din [679]

Answer:

cerebral cortex

Explanation:

The tissue through which the messages are relayed between different areas of the grey matter is termed the white matter.
The nerve fibers present in the white matter are surrounded by myelin due to which they appear white and hence, the name.
White matter is present in deeper parts of the brain and on the superficial parts of the spinal cord in the central nervous system.
White matter under normal conditions is absent from the cerebral cortex.
