(a) fibroblasts
(b) histocytes
(c) lymphocytes
(d) mast cells

Explanation:
1. Mast cells of the connective tissue secrete histamine in mammals.

Teacher's Note:
1. Fibroblasts form fibres.
2. Histiocytes (macrophages) engulf germs.

Question 7: Ligament is a
(a) modified yellow elastic fibrous tissue
(b) inelastic white fibrous tissue
(c) modified white fibrous tissue
(d) None of the above
Show Answer & Explanation

Answer: (b) inelastic white fibrous tissue

Explanation:
1. Ligaments join bones to bones and are made of inelastic white fibrous tissue (dense regular connective tissue).

Teacher's Note:
1. Elastic ligaments also exist but are rare.
2. Tendons join muscles to bones.

Question 8: Tendon is made up of
(a) adipose tissue
(b) modified white fibrous tissue
(c) areolar tissue
(d) yellow fibrous connective tissue
Show Answer & Explanation

Answer: (b) modified white fibrous tissue

Explanation:
1. A tendon is made of modified white fibrous tissue, strong and inelastic.

Teacher's Note:
1. It joins muscle to bone.
2. Yellow elastic tissue is in ligaments of vertebrae.

Question 9: Simple epithelium is a tissue in which the cells are
(a) hardened and provide support to the organ
(b) cemented directly to one another to form a single layer
(c) continuously dividing to provide form to an organ
(d) loosely connected to one another to form an irregular organ
Show Answer & Explanation

Answer: (b) cemented directly to one another to form a single layer

Explanation:
1. Simple epithelium is a single layer of cells, cemented to one another and resting on a basement membrane.

Teacher's Note:
1. Compound epithelium is multilayered.
2. It lines body cavities.

Question 10: A piece of bone such as femur of frog if kept in dilute HC1 for about a week will
(a) assume black colour
(b) shrink in size
(c) turn flexible
(d) crack into pieces
Show Answer & Explanation

Answer: (c) turn flexible

Explanation:
1. Dilute HCl dissolves the calcium salts from bone, leaving the organic matter, so the bone becomes flexible.

Teacher's Note:
1. Ossein remains.
2. Heating would leave only the minerals.

Question 11: During an injury nasal septum gets damaged and for its recovery which cartilage is preferred?
(a) Hyaline cartilage
(b) Elastic cartilage
(c) Calcified cartilage
(d) Fibrous cartilage
Show Answer & Explanation

Answer: (a) Hyaline cartilage

Explanation:
1. The nasal septum is made of hyaline cartilage, which is the preferred type for repair.

Teacher's Note:
1. Elastic cartilage is in the pinna and epiglottis.
2. Fibrous cartilage is in intervertebral discs.

Question 12: Which cells do not form layer and remain structurally separate?
(a) Epithelial cells
(b) Muscle cells
(c) Nerve cells
(d) Gland cells
Show Answer & Explanation

Answer: (c) Nerve cells

Explanation:
1. Nerve cells remain structurally separate and do not form sheets or layers, unlike epithelial, muscle or gland cells.

Teacher's Note:
1. Neurons connect by synapses.
2. They are specialised for conduction.

Question 13: Which one of the following contains the largest quantity of extracellular material?
(a) Myelinated nerve fibres
(b) Striated muscle
(c) Areolar tissue
(d) Stratified epithelium
Show Answer & Explanation

Answer: (c) Areolar tissue

Explanation:
1. Areolar connective tissue contains a large amount of matrix with few cells, so it has the most extracellular material.

Teacher's Note:
1. Epithelium has little matrix.
2. Nerve fibres and striated muscle have very little.

Question 14: What used to be described as Nissl’s granules in a nerve cell are now identified as

2. Ligaments join bones to bones.

Question 17: In which one of the following preparations are you likely to come across cell junctions most frequently?
(a) Ciliated epithelium
(b) Thrombocytes
(c) Tendon
(d) Hyaline cartilage
Show Answer & Explanation

Answer: (a) Ciliated epithelium

Explanation:
1. Ciliated epithelial cells are held by many cell junctions (tight, adhering and gap junctions).

Teacher's Note:
1. Thrombocytes are cell fragments.
2. Tendon and cartilage have cells scattered in matrix.

Question 18: Which one of the following is the correct matching of three items and their grouping category? Truem Items Group
(a) actin, myosin, rhodopsin muscle proteins
(b) cytosine, uracil, thiamine pyrimidines
(c) malleus, incus, cochlea ear ossicles
