A Lipofuscin granules are found in nerve cell. It is a fine yellow brown pigment granules composed of lipid-containing residues of lysosomal digestion. It is considered to be one of the aging or "wear-and-tear" pigmentsfound in nerve cellsliverkidney etc.

Cardiac muscles contract :
1 quickly and they fatigue
2 quickly and unfatigued
3 slowly and are not fatigued
4 slowly and they fatigue
Explanation:
B The sinoatrial node is the site of electrical activity that causes cardiac muscle contraction. As a result of stimulation that spreads from the sinoatrial nodeeach cardiac muscle cell fibres an action potentialwhich causes the muscle cell to contract. The hearts muscles are cardiac. These striated muscles are uncontrollable. They never get tired and they work nonstop.

Striated muscles contract because of :
1 Sliding of myosin rods on actin rods
2 Sliding of actin rods on myosin rods
3 actin rods coming close to each other
4 myosin rods coming close to each other
Explanation:
B Striated muscles contract because of sliding of actin rods on myosin rods. The sliding filament theory explains the process of muscle contraction according to which contraction of a mucles fibre takes place by the sliding of the actin over the myosin.

Which among the following is not skeleton eye muscle?
1 Medial reetus
2 Lateral reetus
3 Ciliary muscle
4 Oblique muscle
Explanation:
C Ciliary muscle is not skeleton eye muscleit is an intrinsic muscle of the eyeformed as a ring of smooth muscle in the eye's middle layeruvea (vascular layer) which controls accommodation for viewing objects at varying distances and regulates the flow of aqueous humor into Schlemm's canal.
