Cardiac muscle is found is
- (a)
pericardium
- (b)
endocardium
- (c)
myocardium
- (d)
peritoneum
The wall of heart has three layers epicardium, myocardium and endocardium. Myocardium consists of cardiac muscles. These muscles contract quickly and do not get fatigued. Pericardium is the membrane surrounding the heart.
Debove's membrane is a layer of
- (a)
muscular tissue
- (b)
epithelial tissue
- (c)
connective tissue
- (d)
All of these
Debove's membrane layer is present between the epithelium and basement tissue of respiratory and intestinal epithelium. This is formed by connective tissues. Epithelial tissue forms lining and covering e.g., covering of surface and lining of the cavity, like squamous epithelium forms lining of blood vessels.
Keratinised dead layer of skin is made of
- (a)
stratified squamous epithelium
- (b)
simple cuboidal epithelium
- (c)
simple columnar epithelium
- (d)
stratified columnar epithelium
Stratified squamous epithelium is seen in the adult human body. It may be keratinised or non-keratinised. In keratinised stratified squamous epithelium, the outer few layers contain a hard waterproof in their cytoplasm.
Agranulocytes are
- (a)
lymphocytes and monocytes
- (b)
eosinophils and basophils
- (c)
lymphocytes and eosinophils
- (d)
basophils and monocytes
Agranulocytes formed in spleen and lymph nodes are non-granular white blood cells that contain non-lobulated nuclei. These form about 35% of total leucocytes (3.5X109/L). These are two types, i.e., monocytes and lymphocytes.
which of the following cells are round and biconcave in shape?
- (a)
White blood cells
- (b)
Red blood cells
- (c)
Columnar epithelial cells

Mesophyll cells
Red blood cells (RBCs) or erythrocytes are the most abundant of all the cells in blood. They are deviod of nucleus in most of the mammals and are round or biconcave in shape. It is biconcave, because such a shape has increase surface area (for O2 transfer) and allows easy squeezability of the RBCs through the blood vessels.

Nerve cell
- (b)
Red blood cell
