Multiple Choice Questions

Question 1: Extremities of long bones possess cartilage
(a) calcified
(b) fibrous
(c) elastic
(d) hyaline
Show Answer & Explanation

Answer: (d) hyaline

Explanation:
1. The ends of long bones are covered with hyaline cartilage, which reduces friction at joints.

Teacher's Note:
1. Articular cartilage is hyaline.
2. It has no blood supply.

Question 2: A deltoid ridge occurs in
(a) radius
(b) ulna
(c) femur
(d) humerus
Show Answer & Explanation

Answer: (d) humerus

Explanation:
1. The deltoid ridge (tuberosity) for the attachment of the deltoid muscle is on the humerus.

Teacher's Note:
1. Deltoid is the shoulder muscle.
2. Humerus is the upper arm bone.

Question 3: Which ion is essential for muscle contraction?
(a) Na
(b) K
(c) Ca
(d) Cl ter Specific COMOTION AND MOVEMENT
Show Answer & Explanation

Answer: (c) Ca

Explanation:
1. Calcium ions released from the sarcoplasmic reticulum bind troponin and expose the myosin binding sites on actin, which starts contraction.

Teacher's Note:
1. Muscle contraction needs Ca2+ and ATP.
2. Calcium is pumped back for relaxation.

Question 4: Which is a part of pectoral girdle?
(a) Glenoid cavity
(b) Sternum
(c) Ilium
(d) Acetabulum
Show Answer & Explanation

Answer: (a) Glenoid cavity

Explanation:
1. The pectoral girdle consists of the scapula and clavicle.
2. The glenoid cavity is a part of the scapula where the humerus fits.

Teacher's Note:
1. Glenoid cavity is on the scapula.
2. Acetabulum and ilium belong to the pelvic girdle.

Question 5: Which one of the following is a skull bone?
(a) Atlas
(b) Coracoid
(c) Arytenoid
(d) Pterygoid Truem
Show Answer & Explanation

Answer: (d) Pterygoid Truem

Explanation:
1. The pterygoid is one of the bones of the skull.
2. The atlas is a vertebra, the coracoid is a pectoral girdle bone in some vertebrates, and the arytenoid is a laryngeal cartilage.

Teacher's Note:
1. Skull has cranial and facial bones.
2. Atlas supports the skull.

Question 6: Which of the following pairs, is correctly matched?
(a) Hinge joint—between vertebrae
(b) Gliding joint—between zygapophyses of the successive vertebrae
(c) Cartilaginous joint—skull bones
(d) Fibrous joint—between phalanges
Show Answer & Explanation

Answer: (b) Gliding joint—between zygapophyses of the successive vertebrae

Explanation:
1. Gliding joints occur between the articular processes (zygapophyses) of successive vertebrae, allowing sliding movement.
2. Cartilaginous joints are between vertebrae, and skull bones form fibrous (fixed) joints.

Teacher's Note:
1. Know the joint types and examples.
2. Hinge joints are at the knee and elbow.

Question 7: Which one of the following pairs of chemical substances, is correctly categorized ?
(a) Pepsin and prolactin - Two digestive enzymes secreted in stomach
(b) Troponin and myosin - Complex proteins in striated muscles
(c) Secretin and rhodopsin - Polypeptide hormones
(d) Calcitonin and thymosin - Thyroid hormones
Show Answer & Explanation

Answer: (b) Troponin and myosin - Complex proteins in striated muscles

Explanation:
1. Troponin and myosin are complex proteins of striated muscle.
2. Pepsin is an enzyme but prolactin is a hormone, secretin is a hormone but rhodopsin is a pigment, and thymosin is a thymus hormone.

Teacher's Note:
1. Contractile proteins are actin, myosin, troponin and tropomyosin.
2. Myosin has ATPase activity.
