Weekly Quiz Competition

Question 1
1 / -0

The ends of the two bones are connected by

A
Muscles

B
Tendons

C
Cartilages

D
Ligaments

Solution

The ends of the two bones are connected by ligaments. The ends of the bone and muscle are connected by tendons.
Hence, option d is correct.
Question 2
1 / -0

Which of the following is true about cardiac muscle cells?

A
They lack an orderly arrangement of actin and myosin filaments

B
They have less extensive sarcoplasmic reticulum and thus contract more slowly than smooth muscle.

C
They are connected by intercalated discs, through which action potentials spread to all cells in the heart.

D
They have a relatively low sodium permeability with resting potentials more positive than an action potential threshold
Solution
- Each cardiac muscle has a single centrally located nucleus.
- Cardiac muscle cells are striated due to a similar arrangement of contractile proteins.
- They mainly function in the pumping of oxygen-rich blood throughout the body to provide cells with vital nutrients.
Question 3
1 / -0

Choose the correct answer from the alternatives given.
The __ produces white blood cells, which function in __ and __.

A
liver; oxygen transport; defense

B
lymph nodes; oxygen transport; pH stabilization

C
bone marrow; housekeeping; defense

D
bone marrow; PH stabilization; defense

Solution

The bone marrow produces white blood cells which function in housekeeping and defense by fighting against the invading pathogens.
So, the correct option is 'bone marrow; housekeeping; defense'.
Question 4
1 / -0

Choose the correct answer from the alternatives given.
After oxygen diffusion into pulmonary capillaries, it diffuses into, and binds with

A
interstitial fluid; red blood cells

B
interstitial fluid; carbon dioxide

C
red blood cells; haemoglobin

D
red blood cells; carbon dioxide

Solution

Oxygen diffuses through the capillaries in the lung alveoli (the pulmonary capillaries) and binds to the protein haemoglobin present in the red blood cells. Hemoglobin is made up of four subunits and each haemoglobin molecule can bind up to four oxygen molecules. So, the correct option is 'red blood cells; haemoglobin'.
Question 5
1 / -0

Synaptic vesicles are seen

A
at the ends of dendrites and axons

B
at the ends of axons only

C
along the length of all long fibres

D
all of the above

Solution

In a neuron, synaptic vesicles store various neurotransmitters that are then released at the synapse. The release is regulated by voltage-dependent calcium channel. Vesicles are seen at synaptic junctions at the end of axons.
So, the correct option is B.
Question 6
1 / -0

Choose the correct answer from the alternatives given.
Grey matter is

A
located on the outside of the spinal cord

B
restricted to the brain

C
populated by cell bodies of neurons

D
found in the ventricles of the vertebrate brain

Solution

Grey matter is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil, glial cells, synapses, and capillaries.
So, the correct option is 'populated by cell bodies of neurons'.
Question 7
1 / -0

Macrophages are derived from

A
Basophils

B
Monocytes

C
Neutrophils

D
Eosinophils

Solution

Macrophages are scavenging cells derived from monocytes and are found all over the body. These infiltrate the tissue during an inflammatory response.
So, the correct option is 'Monocytes'.
Question 8
1 / -0

'Mummies' of Egypt still have their arteries preserved due to the presence of

A
Yellow elastic connective tissues fibres

B
White fibrous connective tissue fibres

C
Cartilage

D
Valves

Solution

Yellow elastic connective tissue fibres are present in the wall of blood vessels, lungs, bronchioles, cartilage of larynx and trachea, etc. These fibres have considerable strength and remarkable elasticity. 'Mummies' of Egypt still have their arteries intact due to the presence of these fibres.
So, the correct answer is option A.
Question 9
1 / -0

Biceps muscles connect humerous with the ________

A
Radius, ulna

B
Tibia, fibula

C
Pectoral girdle

D
Skull

Solution

The biceps, also known as biceps brachii lies on the front of the upper arm between the shoulder and the elbow. The biceps brachii has two heads, or origins. Both heads originate on the scapula. The long head attaches to the supraglenoid tubercle of the scapula, which is just above the space where the humerus, or upper arm, enters the shoulder. The short head attaches to the coracoid process of the scapula. Both heads converge into one muscle, that runs the length of the humerus. The biceps brachii crosses the inside of the elbow and attaches at the radial tuberosity, which is a feature on the radius - one of the two bones (Ulna is other bone) in- the lower arm. In this way it attaches humerus with the radius and ulna.
So, the correct option is 'Radius, ulna'.
Question 10
1 / -0

Which of the following statement is/are not correct regarding connective tissue?

(i) They are the most abundant and widely distributed in the body of complex animals.
(ii) They connect and support other tissues.
(iii) They include diverse tissues such as bones, cartilage, tendons, adipose, and other loose connective tissues.
(iv) They form the internal and external lining of many organs.
(v) Blood is an example of a fluid connective tissue.

A
(iv) only

B
(v) only

C
(i) and (ii)

D
(ii) and (v)

Solution

The internal and external lining of organs is formed by different types of epithelial tissue, based on the function of the organ. Example, alveoli- exchange of gases- squamous epithelium, skin-protection - keratinised epithelium and so on... . The function of different types of connective tissue is transport substances between various tissues and organs in the body (blood), bind tissue together (loose and dense) and to provide support (bone and cartilage), that i's they do not form linings of body organs.
All the other statements about connective tissue are true.
So, the correct answer is '(iv) only'
