Multiple choice

Langerhans cells are found in the epidermis layer of the skin. These are generally found in

  1. lymph

  2. lymph nodes

  3. periarteriolar lymphoid sheaths

  4. skin

  5. mantle zone
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Langerhans' cells in the skin pick up and process antigen, then travel as veiled cells in the lymph before becoming interdigitating dendritic cells in the paracortical T-cell zone of the draining lymph node, where they are potent stimulators of T-cell responses.

Multiple choice

Small oval-shaped structures found in the lymphatic vessels are termed

  1. valves

  2. lymph nodes

  3. lacteals

  4. lymph movement
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Lymph nodes are oval or bean-shaped bodies placed in the lymphatic vessels. They act as filters and are sites where lymphocytes are formed. The main groups of lymph nodes lie in the neck, axilla, thorax, abdomen and groin.

  1. connective tissue

  2. nervous tissue

  3. epithelial tissue

  4. muscular tissue
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Epithelial tissue is of two types: simple epithelium and compound epithelium. Simple epithelium is divided as squamous, cuboidal, columnar, ciliated and pseudo stratified.

Multiple choice

Which part of the respiratory system is called windpipe?

  1. Pharynx

  2. Larynx

  3. Trachea

  4. Bronchioles

  5. Alveoli
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The trachea or windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air. The trachea begins immediately below the larynx (voice box) and runs down the center of the front part of the neck and ends behind the upper part of the sternum. Here, it divides to form two branches that enter the lung cavities. The trachea is made up of fibrous and elastic tissues and smooth muscle.

Multiple choice

A human penis lacks

  1. corpus cavernosa

  2. seminiferous tubules

  3. corpus spongiosum

  4. glans
Reveal answer Fill a bubble to check yourself
B Correct answer

Multiple choice

Among the following which one is a pear-shaped female reproductive organ?

  1. Vulva

  2. Vagina

  3. Uterus

  4. Oviducts
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

It is defined as a pear-shaped organ, broader on the upper end and narrower on the lower end. The upper end is called the body of the uterus and the lower end is called the cervix. At the upper end, it communicates with the oviducts of either side whereas the cervix connects into the vaginal canal which opens to the outside.

Multiple choice
