A group of students are reviewing the anatomy and physiology of the breasts. The students demonstrate understanding of breast structure when they identify the tail of Spence as an extension of which quadrant?

The upper lateral quadrant.

Explanation:

The breast is a glandular and fatty tissue that lies on the top of the pectoral muscles of the chest. It is made up of fatty tissues, glands, and connective tissue ligaments that attach it to the muscles.

The glands are the functional units as they are where the milk is produced. These glands are divided into 15 to 20 lobes of glands demarcated by fatty and connective tissues. Each lobe is made up of lobules where milk is produced. They are various ducts that carry the milk and they open up on the nipple.

The breast is usually divided into four imaginary quadrants during clinical examination. The upper lateral quadrant has an extension of breast tissues into the armpit. This is referred to as the Tail of Spence or axillary tail.

The tail of Spence has axillary lymph nodes around it and plays a key role in the diagnosis of breast cancer.

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
