A dense outer layer of vascular connective tissue enveloping the bones except at the surfaces of the joints is the:

1. epiphysis

2. diaphysis

3. articular cartilage

4. periosteum

When a bone bends and cracks, instead of breaking completely into separate pieces, the fracture is called as:

1. greenstick

2. incomplete

3. compound

4. simple

Given these types of joints:

a. gomphosis
b. suture
c. symphysis
d. synchondrosis
e. syndesmosis

Choose the types that are held together by fibrous connective tissue.

1. a, b, c

2. a, b, e

3. b, c, e

4. c, d, e
 

Given these types of joints:

1 gomphosis
2 suture
3 symphysis
4 synchondrosis
5 syndesmosis

Choose the types that are held together by cartilage.

1. 1,2

2. 1,4

3. 2,3

4. 3,4
 

The primary cartilaginous joints and the secondary cartilaginous joints are respectively called:

1. sutures; synchondroses

2. syndesmoses; symphyses

3. symphyses; syndesmoses

4. synchondroses; symphyses

A space between the bones of the skull in an infant or fetus, where ossification is not complete and the sutures not fully formed is called a:

1. synchondrosis.

2. syndesmosis.

3. symphysis.

4. fontanel.

The articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage but their stability is due to the presence of:

1. fascia.

2. joint capsule.

3. tendon sheath.

4. aponeurosis.

If a stimulus, several times greater than the threshold stimulus, is provided to a muscle fiber, it will
1. Contract with a larger force
2. Contract with a smaller force
3. Contract with the same force
4. Undergo tetany

Assertion: Calmodulin plays an important role in excitation contraction (EC) coupling and the initiation of the cross-bridge cycling in smooth muscle.
Reason: Troponin is not found in the smooth muscles.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.

Assertion: Myoglobin needs to have a higher affinity for oxygen than hemoglobin.
Reason: To perform its job, myoglobin must effectively bind any oxygen released from hemoglobin.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false.
