Animal Tissue and Anatomy Questions

Multiple choice

The innermost layer of the mucosa is

  1. serous membrane

  2. muscular coat

  3. mucosa

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

Mucosa is the extensively folded innermost layer. It can be divided into the epithelium, lamina propria, and the muscularis mucosae, though some consider the outermost muscularis mucosae to be a distinct layer, as it develops from the mesoderm rather than the endoderm (thus making a total of five layers).

Multiple choice

Haustra is found in

  1. caecum

  2. colon

  3. the appendix

  4. the rectum
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Colon, representing the greater part of the large intestine, consists of four sections: the ascending, transverse, descending, and sigmoid colons. At regular distances along the colon, the smooth muscle of the muscularis layer causes the intestinal wall to gather, producing a series of pouches called haustra.

Multiple choice

Multiple choice

Vagina is the

  1. sexual organ of females

  2. muscular tube

  3. Both A and BSexual organ of males

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Multiple choice

The linings of fallopian tubes, alimentary canal and small intenstine are formed by

  1. Simple pseudo-stratified epithelium

  2. Simple cylindrical epithelium

  3. Cuboidal epithelium

  4. Squamous epithelium
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Simple cylindrical epithelial tissues can be found mainly in fallopian tubes, alimentary canal and small intenstine. Cells developing in fallopian tubes have cilia that make movements in uterus easier, and those developing in small intenstine contain microvilli that enlarge absorption surface. Cells of that tissue are prism-shaped. Nucelus is at the cell bottom.

Multiple choice

Which of the following statements is wrong regarding the epithelial tissue?

  1. Does not participate in excretion

  2. Plays active role in protection

  3. Helps in diffusion

  4. Reduces friction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Epithelial tissues in the kidney excrete waste products from the body and reabsorb needed materials from the urine. Sweat is also excreted from the body by epithelial cells in the sweat glands.

Multiple choice

Which of the following is a vestigial organ in humans?

  1. Vermiform appendix

  2. Cervical vertebra

  3. Atlas

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

 Vermiform appendix is a vestigial organ in humans.It is a blind-ended tube connected to the cecum, from which it develops embryologically. The cecum is a pouchlike structure of the colon, located at the junction of the small and the large intestines.

Multiple choice

The response of an organism towards a current in a fluid is known as

  1. Thermotaxis

  2. Geotaxis

  3. Rheotaxis

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

Rheotaxis is a response to a current in a fluid. Positive rheotaxis is shown by fish turning to face against the current. In a flowing stream, this behaviour leads them to hold their position in a stream rather than being swept downstream. Some fish will exhibit negative rheotaxis where they will avoid currents.
