Question 1
1 / -0

The intestine and kidney in human beings are lined by which type of cells?

A
Ciliated

B
Brush bordered

C
Keratinised

D
Squamous

Solution

A brush border (striated border or brush border membrane) is the microvilli-covered surface of simple cuboidal epithelium and simple columnar epithelium cells found in certain locations of the body. Due to its appearance similar to the bristles of a brush, it is named as 'Brush bordered'. This type of lining is mainly found in the small intestine tract, the kidneys and also in the large intestine.
So, the correct answer is B.
Question 2
1 / -0

Largest smooth muscles occur in ______________.

A
Urethra

B
Uterus of pregnant woman

C
Leg

D
Thigh

Solution

B. Uterus of pregnant woman
EXPLANATION: Largest smooth muscle is present in the uterus of pregnant woman. It is the strongest muscle in the human body. The uterus is located within the pelvic region and almost overlaying the bladder and in front of the sigmoid colon.
Question 3

Column I Column II
a Simple Columnar Epithelium p Wall of Heart
b Cardiac Muscle q Bone joints
c Adipose tissue r Inner lining of Stomach and Intestine
d Hyaline Cartilage s Below the skin in abdomen
t Diaphram
Match the columns.

A
a-r, b-p, c-s, d-q

B
a-r, b-t, c-q, d-s

C
a-p, b-r, c-s, d-t

D
a-r, b-p, c-t, d-s
Solution
1. Simple Columnar Epithelium is found in most organs of the digestive tract including the inner lining of the stomach and small and large intestine.
2. Cardiac muscle, also known as heart muscle is an involuntary, striated muscle that constitutes the main tissue of the walls of the heart.
3. Adipose tissue is found in various places in the body locations - the subcutaneous layer under the skin; around the heart, kidneys, Below the skin in the abdomen.
4. Hyaline cartilage is high in collagen and is found at joints.
  So option A is correct.
Question 4
1 / -0

Choose the wrong statement with reference to smooth muscles.

A
Muscle fibres show alternate dark and light bands.

B
They are spindle-shaped uninucleate cells.

C
They are involuntary muscles.

D
They are found in the iris of the eye.

Solution

Muscle fibres of smooth muscle do not show striations which means they do not have alternate light and dark bands, like in skeletal muscles.
So, the correct option is A.

Question 5

1 / -0

Match the lists.

	I		II
(a)	Simple squamous epithelium	(i)	Ureters
(b)	Simple cuboidal epithelium	(ii)	Epididymis
(c)	Nonciliated simple columnar epithelium	(iii)	Lining of alveoli of lungs
(d)	Transitional epithelium	(iv)	Lining of thyroid vesicles
(e)	Pseudostratified nonciliated columnar epithelium	(v)	Mucosa of stomach and intestine

(a)-(iii), (b)-(iv), (c)-(v), (d)-(i), (e)-(ii)

(a)-(i), (b)-(ii), (c)-(iv), (d)-(iii), (e)-(v)

(a)-(v), (b)-(iii), (c)-(ii), (d)-(iv), (e)-(i)

(a)-(ii), (b)-(iv), (c)-(iii), (d)-(v), (e)-(i)

Solution

[a] Simple squamous epithelium is found in alveoli of lungs, capillaries, glomeruli, and other tissues where rapid diffusion is required.

[b] Simple cuboidal epithelium is found in thyroid glands, kidney tubules, glandular ducts and ovaries, and the thyroid gland.

[c] Non-ciliated simple columnar epithelium lines the organs of the digestive tract including the stomach, small intestine, and large intestine.

[d] The transitional epithelium is found in the urinary bladder, ureters, and gland ducts of the prostate.

[e] Pseudostratified non-ciliated columnar epithelium lines the epididymis of the male reproductive system.

So, (a)-(iii), (b)-(iv), (c)-(v), (d)-(i), (e)-(ii)

Therefore, the correct answer is option A.

Question 6
1 / -0

Epimysium, perimysium and endomysium occur in ______________.

A
Blood vessel

B
Striated muscle

C
Nerve

D
Uterus

Solution

Striated muscles are the voluntary muscles which have overlapping contractile myofilaments. These are made up of a contractile protein known as actin and myosin.
The connective tissue which wraps the whole muscle is termed as epimysium. It is a fibrous elastic type of tissue.
Perimysium is the connective tissue that wraps bundles of muscle fibres.
Endomysium is the layer of areolar connective tissue. It ensheaths each individual muscle fibre. It also contains capillaries, nerves, and lymphatics.

So, the correct option is B.
Question 7
1 / -0

Function of ampulla of spermatheca is

A
To store sperms

B
To nourish sperms

C
To secrete sticky material during copulation

D
None of the above

Solution

The purpose of spermatheca is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body. The sperms stored in the spermatheca is nourished by ampulla.
So, the correct answer is 'To nourish sperms'.
Question 8
1 / -0

The nature of chaetae of earthworm is

A
Chitin

B
Cellulose

C
Protein

D
Chitin and scleroprotein

Solution

Chaetae in earthworm occur in small groups projecting from the skin in each segment and function in locomotion. They are made of chitin and scleroprotein. So, the correct answer is 'Chitin and scleroprotein'.
Question 9
1 / -0

Cardiac muscle occurs in _______________.

A
Epicardium

B
Endocardium

C
Myocardium

D
All the above

Solution

A. The epicardium is the outermost layer of our heart
B. The endocardium is the innermost layer of our heart. It lines the inner surfaces of the heart chambers which also includes the heart valves.
C. The cardiac muscle layer of the heart is known as the myocardium. These are made up of cardiomyocytes. The myocardium is found in the walls of all four chambers of the human heart.

So the correct answer is Myocardium. Thus the correct option is C.
Question 10
1 / -0

Which is not a neuroglial cell?

A
Oligodendrocyte

B
Microglia

C
Astrocyte

D
Chondrocyte

Solution

The neuroglia or glial cells are defined as supportive cells of the central nervous and peripheral nervous system that primarily support, protect and nourish the neurons. There are basically four types of neuroglial cells:-
Astrocytes, Oligodendrocytes, Microglia and Ependyma.While Chondrocytes are cells that make up the dense connective tissue that is present in the cartilage matrix.
So, the correct answer is 'Chondrocyte'.
