Characteristics: Contain simple cuboidal epithelium

Question 6

Name & Characteristics

Answer 6

Urethra

Characteristics: The epithelium of the urethra starts off as transitional cells as it exits, further along the urethra there are stratified columnar cells, then stratified squamous cells near the external urethral orifice.

There are small mucus-secreting urethral glands, that help protect the epithelium from the corrosive urine.

Answer 14

Colon

Characteristics – Divided into four layers- mucosa, submucosa, muscularis externa and serosa. The mucosa is the innermost layer of the gastrointestinal tract that is surrounding the lumen, or space within the tube. This layer comes in direct contact with food (or bolus), and is responsible for absorption and secretion. Mucosa is further divided into epithelium, lamina propria and muscularis mucosae

Characteristics: “1” is anterior pituitary (pars distalis), “2” is pars nervosa (neurohypophysis), and “3” is the infundibulum connecting pars nervosa to the hypothalamus

Question 18

Name & Characteristics

Answer 18

Oral Cavity

Characteristics - The oral mucosa is the mucous membrane epithelium of the mouth. It can be divided into three categories.

Masticatory mucosa - keratinized stratified squamous epithelium, found on the dorsum of the tongue, hard palate and attached gingiva.

Lining mucosa - non-keratinized stratified squamous epithelium, found almost everywhere else in the oral cavity.

Specialized mucosa - specifically in the regions of the taste buds on the dorsum of the tongue.

Question 19

Name & Characteristics

Answer 19

Lymph Node

Characteristics – A lymph node is round, ovoid, or bean-shaped and varies in size from less than 1 mm to 2-3 cm. Lymph nodes may enlarge during infection or disease and then they are easily palpated.

Answer 21

Crypts of Lieberkuhn

Characteristics: composed of simple columnar cells, goblet cells, DNES, and Paneth cells; tubular glands

Question 22

Name & Characteristics

Answer 22

Pineal Gland

Characteristics: The secretory cells of the pineal gland are pinealocytes. The pineal body consists in humans of a lobular parenchyma of pinealocytes surrounded by connective tissue spaces. The gland’s surface is covered by a capsule.

Question 23

Name & Characteristics

Answer 23

Thymus

Characteristics - Thymus is a bilobed mass of lymphatic tissue. It reaches its greatest relative weight (10-15 g) at birth and its greatest absolute weight (30-40 g) about the time of puberty. It begins to involute after puberty (weighing about 25 g at 25 years, 13 g at 50 years, and 6 g at 75 years) and may become difficult to recognize grossly because of fatty infiltration. Gonads, suprarenal glands, and the thyroid gland influence the thymus.
