Animal Tissue and Anatomy Questions

Multiple choice

The epithelium tissue associated with the kidney tubules as well as in the ducts of the glands is ________________.

  1. simple cuboidal epithelium

  2. stratified epithelium

  3. glandular epithelium

  4. ciliated columnar epithelium

  5. simple columnar epithelium
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cuboidal cells are roughly square or cuboidal in shape. Each cell has a spherical nucleus in the centre. Cuboidal epithelium is found in glands and in the lining of the kidney tubules as well as in the ducts of the glands.

Multiple choice

In humans, the inner lining of the mouth, esophagus, and vagina is formed by a _____________.

  1. simple squamous epithelium

  2. stratified squamous epithelium

  3. stratified cuboidal epithelium

  4. stratified columnar epithelium

  5. pseudostratified epithelium
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. It forms the outermost layer of the skin and the inner lining of the mouth, esophagus and vagina.

  2. A flap-like epiglottis closes the opening to the larynx during swallowing.

  3. The cricoid cartilage is the only complete ring of cartilage in the trachea.

  4. The trachea is lined with pseudostratified columnar epithelium.

  5. There are fifteen to twenty incomplete C-shaped tracheal rings of cartilage.

A Correct answer
Explanation

The oesophagus lies posteriorly to the trachea. Circular bands of fibrous connective tissue called the annular ligaments of trachea join the tracheal rings together.

Multiple choice

Adam's apple is a forward protrusion of the largest cartilage of the larynx. Which among the following cartilages form(s) Adam's apple?

  1. Cricoid cartilage

  2. Thyroid cartilage

  3. Corniculate cartilages

  4. Cuneiform cartilages

  5. Arytenoid cartilages
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This forms the Adam's apple. It is usually larger in males than in females. The thyrohyoid membrane is a ligament associated with the thyroid cartilage that connects the thyroid cartilage with the hyoid bone.

Multiple choice

Which among the following structures of male reproductive system enters the prostate gland to empty into the urethra?

  1. Seminal vesicle

  2. Ampulla

  3. Ejaculatory duct

  4. Epididymis

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

The ejaculatory duct in males is formed by a union of the ampulla of the ductus deferens and the duct of the seminal vesicle. This duct receives secretions from the seminal vesicle and prostate gland and penetrates the prostate gland where it empties into the urethra.

Multiple choice

Which of the following cartilages forms Adam's apple in adult human male?

  1. Cricoid cartilage

  2. Thyroid cartilage

  3. Corniculate cartilages

  4. Arytenoid cartilages

  5. Cuneiform cartilages
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This forms the Adam's apple. It is usually larger in males than in females. The thyrohyoid membrane is a ligament associated with the thyroid cartilage that connects the thyroid cartilage with the hyoid bone.
