The bone not included in neurocranium is:

1.	frontal	2.	ethmoid
3.	sphenoid	4.	zygomatic

The clavicle articulates with:
1. first rib and thoracic vertebra
2. humerus and sternum
3. cervical rib and sternum
4. scapula and sternum

A muscle fasciculus is surrounded by:

The extensions of the cell membrane that penetrate into the centre of skeletal and cardiac muscle cells are called as:

The majority of the muscle fibers in the skeletal muscles of the leg of a long distance runner is expected to have:
1. adaptation for sudden outburst of activity
2. primarily anaerobic source of energy
3. numerous mitochondria
4. large deposits of glycogen

The synovial joint that allows maximum movements is:

Even when the blood supply is inadequate, the muscle is able to sustain contraction due to:

Immediately after the motor neuron passes an impulse to a muscle fiber:
1. the impulse travels over the sarcolemma in all directions.
2. calcium is released from the sarcoplasmic reticulum.
3. cross bridge forms between the actin and myosin.
4. troponin undergoes a conformational change.

Identify the incorrect statement:
1. A muscle fiber contracts in an all-or-none fashion.
2. A slight delay occurs between the reaching of impulse at the neuromuscular junction and muscle contraction.
3. Using more motor units will increase the overall force of contraction.
4. When a person is fully at rest, none of her muscles are contracting.

Identify the correct statement regarding the comparison of skeletal and smooth muscle:
1. Nervous stimulation of smooth muscle is always excitatory, whereas nervous stimulation of skeletal muscle may be excitatory or inhibitory.
2. The contractile activity of smooth muscle may be affected by hormones, whereas the contractile activity of the skeletal muscle is not.
3. Both ANS and somatic neural systems innervate smooth muscle, whereas skeletal muscle may be innervated by the somatic motor system only.
4. The calcium-binding protein in smooth muscle is troponin whereas in skeletal muscle, it is tropomyosin.
