Place the layers of the trachea in order from deep to superficial.
a) mucosa, submucosa, hyaline cartilage, adventitia
b) submucosa, mucosa, hyaline cartilage, adventitia
c) adventitia, hyaline cartilage, submucosa, mucosa
d) adventitia, hyaline cartilage, mucosa, submucosa
e) hyaline cartilage, submucosa, mucosa, adventitia

a) mucosa, submucosa, hyaline cartilage, adventitia

Explanation:

The wall of the trachea can be divided into four layers from the deep region to the superfacial region :

These are;  mucosa, submucosa, the musculocartilaginous layer (hyaline cartilage), and the adventitia.

The adventitia is a connective tissue layer that combines with the musculocutaneous layer and with the connective tissue that encircles the trachea. It is composed of loose areolar tissue. This areolar tissue permits a considerable amount of movement of the trachea along its length.

The musculocartilaginous layer consists of the cartilaginous plates, fibroelastic tissue, and the tracheal muscle. The cartilaginous plates number and are composed of hyaline cartilage surrounded by perichondrium.

The submucosa contains many elastic fibers and fat cells and many small seromucous tubular glands, which open into the lumen of the trachea.

The mucosa has numerous low longitudinal folds and is lined with pseudostratified columnar ciliated epithelium, which contains numerous goblet cells and rests on a basement membrane.

I hope that helps!

The correct answer is a) mucosa, submucosa, hyaline cartilage, adventitia.

Explanation:

The trachea is the conduit that allows the passage of air from the outside to the lungs, which is divided at its base into two bronchi.

The walls of the trachea have several layers of tissues, in order from deep to superficial:

Mucosa, has the same goblet cells that contain the pseudostratified epithelia that appear in most of the respiratory tract.

Submucosa, is dense connective tissue and continues with the perichondrium of the hyaline cartilage that constitutes the tracheal rings.

Hyaline cartilage, it is the most widely distributed cartilage. The tracheal cartilaginous ring is open, and the ends are joined by a fibroelastic ligament and bundles of smooth muscle that attach to the perichondrium (the outer layer of cartilage).

Adventitia, is the outermost layer and covers the outer part of the incomplete cartilaginous rings. It is connective tissue that may contain adipose tissue.
