Answer:
Spermatogenesis , Spermatogonia
Explanation:
Gonads are the primary sex organs in the male which are the two testes.
Each testis divide into testicular lobules each containing the sparse connective tissue with the endocrine interstitial cells that secrets testosterone, and also contains one to four highly convoluted seminiferous tubules which is responsible for sperm production.
The process is known as <u>spermatogenesis</u>.
This process begins with mitotic division of stem cells which are located close to basement membrane of tubules. The cells are known as <u>spermatogonial stem cell</u>s. The division produces two types of cells.
Type A cells are the cells which replenish stem cells and type B cells are the cells which differentiate into spermatocytes. They have number of chromosomes = 46.
Noisy breathing is produced by enlarged adenoids.
The lymphoid adenoids are located in the upper airway between the back of the throat and the nose. They resemble tonsils in appearance. Adenoids that are enlarged indicate swelling tissue. The tonsils, esophagus, trachea, and epiglottis are among the components of the throat.
Snoring, mouth breathing, chronic congestion, nasal discharge, ear issues, sinusitis, and "nasal" voice quality can all be signs of an enlarged adenoid.
The rear of the mouth and on either side of the throat are home to the tiny, rounded tonsils. The adenoid is a mass of tissue that is situated above the roof of the mouth, behind the nasal cavity. Adenoids and tonsils combat infections and can expand if they do so.
A bacterial infection, such as one with the bacteria Streptococcus, may be the cause of adenoiditis. Adenovirus, rhinovirus, and Epstein-Barr virus are just a few of the viruses that might cause it.
Enlarged adenoid symptoms are:
- breathing through the nose is challenging.
- Poor breath and chapped lips as a result of mouth breathing.
- having a compressed or stuffed-nose sound.
- recurring nasal issues.
- Snoring.
- Obstructive sleep apnea or restless sleep.
- middle ear infections that recur or fluid buildup in children at school
