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.

What is the degree of the polynomial 3x^5-6x^2+5x?


A ) 8

B ) 7

C ) 2

D ) 5

Answers

Answer:

D.5

Explanation:

i took the test trust me

The degree of the polynomial 3x^5 - 6x^2 + 5x is 5, so the answer is option D.

A polynomial is a type of algebraic expression that consists of variables, coefficients, and exponents.

There can be one or more terms in a polynomial, and the degree of the polynomial is determined by the highest power of the variable present in it.

For example, the polynomial 3x^2 + 4x + 5 has a degree of 2 since the highest power of the variable (x) is 2. In the given polynomial 3x^5 - 6x^2 + 5x, the highest power of the variable is 5, which means that the degree of the polynomial is 5.

Hence, the correct answer is option D.

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.

In the original game, it was virtually impossible to get through to Level 22 before Mario was killed by the game. This was an unintended consequence of how the number of bonus points was calculated and stored.The number of bonus points a player starts with when they move onto a new level depends on the number of the level that they are moving onto. Behind the scenes, Donkey Kong takes the level that is about to be entered, multiplies it by 10 and adds 40, thus yielding the first two digits of the players starting bonus.So, for example, if a player is about to start Level 2, the bonus number is calculated like this:2 10 + 40 = 60.This bonus number is stored in a single byte as an unsigned integer. The bonus number will never be 0. i.Write down and evaluate an expression for the number of different unsigned integers that can be represented in a single byte. Then write down the largest unsigned integer that can be represented if no representation for 0 is required. ii.Find the bonus number associated with Level 22. Explain why storing this bonus number will cause a problem. iii.For Level 22, the bonus number actually stored is 4. Give one likely explanation for this. iv.The bonus number is multiplied by 100 before it is displayed on the screen, so for Level 22 the number displayed on the screen is 400.
