Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Which of the following statements is TRUE?

Carpal tunnel syndrome occurs when the ulnar nerve is compressed.
Carpal tunnel syndrome occurs when the facial nerve is irritated or swollen.
*Carpal tunnel syndrome occurs when the median nerve is compressed.
Carpal tunnel syndrome occurs when the 7th cranial nerve is irritated or swollen.

Answers

Answer:

c. Carpal tunnel syndrome occurs when the median nerve is compressed.

Explanation: is correct

Carpal tunnel syndrome occurs when the median nerve is compressed.

What is Carpal tunnel syndrome?When the median nerve, which travels from the forearm into the palm of the hand, is pinched or compressed at the wrist, carpal tunnel syndrome (CTS) develops. The median nerve and the tendons that bend the fingers are housed in the carpal tunnel, a small, stiff passageway made of ligament and bones at the base of the hand. The index, middle, and part of the ring fingers, as well as the palm side of the thumb, are all sensed by the median nerve (although not the little finger). The tunnel can occasionally become smaller and the median nerve can become compressed due to edema or thickening caused by inflamed tendon lining. As a result, the hand and wrist may experience numbness, weakness, or even pain (some people may feel pain in the forearm and arm). The most prevalent and well-known entrapment neuropathy, in which a peripheral nerve of the body is pushed against or crushed, is CTS.

The anterior rami of spinal nerves ______ are called intercostal nerves because they travel in the intercostal space sandwiched between ______.

Answers

Answer: T1-T11; two adjacent ribs

Explanation:

The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.

What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.

Three types of macromolecules are mentioned in the video that are digested and ABSORBED in the small intestine. What do they all get absorbed into first?

Lacteals

Epithelial cells

Capillaries​

Answers

Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".

The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.

Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

Option 3.

Explanation:

The development of the various stages of stem cells in the embryonic stage is described here:Totipotent stem cells: Right after the mitosis of the zygote which results in the formation of two identical daughter cells, which are totipotent stem cells. Totipotent stem cells possess the ability to give rise to 220 different types of cells in the embryo including the placenta.Pluriopotent stem cells: These types of cells possess the ability to change into any type of cell in the body like blood, muscle, etc. It is formed at the embryonic stem cell stage.Multipotent stem cells: These stem cells have the ability to change into specialized cell such as forming different organs in the body. It occurs as the pluriopotent cell develops in the embryo.Neuron: As the multipotent cell has the ability to form a specialised cell it gives rise to the heart, lungs, liver, etc. including neurons.
