MCQ ON TISSUES -2
Q26: Name different types of white blood corpuscles.
Answer:
Neutrophil (polynuclear leucocyte)
Eosinophil
Basophil
Lymphocyte
Monocyte
Q27: List the functions of blood cells
Answer: Blood flows and transports gases, digested food,
hormones and waste materials
to different parts of the body. Provide various defense activities.
Q28: Where blood is formed in our body?
Answer: In the bone marrow tissue which are present in the
interior of large bones.
Q29: Name the two fluid connective tissues.
Answer:
1. Blood
2. Lymph
Q30: Why type of inter cellular matrix is found in bone tissue?
What are its
constituents?
Answer: Bone cells are embedded in a hard matrix that is
composed of calcium and
phosphorus compounds.
Q31(CBSE): Identify the location of the following connective
tissues.
(a) Blood
(b) Lymph
(c) Bone
(d) Cartilage
(e) Tendons
Answer:
(a) Blood: Present all over the body in blood vessels.
(b) Lymph: Present in lymph vessels
(c) Bone: Present in all over body forming an endoskeleton.
(d) Cartilage: trachea, larynx, ear, tip of nose
(e) Tendons: connect muscles to bones.
Q32: Which connective tissue connects two bones?
Answer: Ligaments.
Q33: Which connective tissue connects bones to muscles?
Answer: Tendons.
Q34: Name the constituents of matrix found in cartilage.
Answer: The solid matrix of cartilage is composed of proteins and
sugars.
Q35: Where do we find Areolar tissue? What are its functions?
Answer: Areolar connective tissue is found between the skin and
muscles, around blood
vessels
and nerves and in the bone marrow. It fills the space inside the
organs, supports internal
organs and helps in repair of tissues.
Q36: Name the fatstoring
tissues? Where are they located? How do these tissue
help?
Answer: Adipose tissues are fatstoring
tissues and are found below the skin and
between internal organs. The cells of this tissue are filled with fat
globules. Storage of
fats also lets it act as an insulator.
Q37: What are different types of muscle tissues? Also list which of
these are
voluntary or involuntary.
Answer: There are three kinds of muscle tissues:
1. Striated Muscles voluntary
muscle
2. Smooth muscle involuntary
muscle
3. Cardiac muscle involuntary
muscle
Q38: Why are striated muscles called skeletal muscles?
Answer: Because they are mostly attached to bones and help in
body movement.
Q39: What are identification marks of striated muscles when seen
under
microscope?
Answer:
muscles show alternate light and dark bands or striations when
stained
appropriately. (that's why these are called striated muscles).
tissue are long, cylindrical, unbranched and multinucleated
(having many
nuclei).
Q40: Identify which type of muscles tissues are associated with
the following body
actions
(a) locomotion
(b) iris movement to control size of pupil
(c) peristaltic movements of the oesophagus
(d) heart beat
(e) movement of blood in blood vessels
Answer:
(a) locomotion: striated muscles
(b) iris movement to control size of pupil: smooth muscles
(c) peristaltic movements of the oesophagus: smooth muscles
(d) heart beat: cardiac muscles
(e) movement of blood in blood vessels: smooth muscles
Q41: How will you identify cardiac muscles cells under a
microscope?
Answer: Cardiac muscle cells are short, branched and striated.
These are usually uninucleated.
Cells are interconnected by intercalated discs.
Q42: Which muscle tissues show characteristics of both striated
and unstriated
muscles?
Answer: Cardiac tissues.
Q43: Where do we find cardiac tissues? What are the functions of
cardiac tissues?
Answer: Cardiac tissues are found in heart only. Cardiac muscle
tissues contract and
relax rhythmically throughout life without fatigue. They pump and
distribute the blood to
the various parts of the body.
Q44: Do all cells respond to stimuli or this ability is possessed by
nerve cells only?
Answer: All cells respond to stimuli. But nerve cells are
specialised in transmitting the
stimulus very
rapidly from one place to another within the body.
Q45: What is the unit of nervous tissues?
Answer: Neuron or nerve cell.
Q46: Where do we find nerve cells?
Answer: Nerve cells are present in the brain, spinal cord and
peripheral nerves are
branched throughout the body.
Q47: How long a nerve cell can be?
Answer: It can be a meter long.
Q48: How are muscles tissues related to nerve cells?
Answer: Muscles do not move on their own. They move only
when they receive a nerve
impulse. Motor neurons ( a type of nerve cell) are connected to
muscles which carry
stimulus for muscle movement.
Q49: Name the three distinct parts of a neuron.
Answer: Cell Body, dendrites, axon
Q50: What is myelin sheath? Where do we find it?
Answer: Axons of nerve cell is covered by a sheath called myelin
sheath. Myelin sheath
prevents the leakage of nerve impulse ( a sort of electrical signal)
from the axon.
Q51: What happens in polio disease?
Answer: During early stages of childhood, when Polio virus
attacks it kills motor neurons.
Also nerve cells lose their ability to reproduce new nerve cells.
This damage is
permanent and the affected kid is unable to walk properly in his
life.
