Question

1 give the structural difference between smooth and cardiac muscle

2 give similarity between

a. cartilage and bone

b. bone and blood

c. striated and cardiac muscle

d. stratified and squamous pithelial tissue

Answer 1

SNo.	Smooth Muscle	Cardiac Muscle
1. 2. 3. 4.	Cells are cylindrical and unbranched. They contain one nucleus per cell. They have tapered ends and donot show straitions. They lack the typical arrangement of the sachromeres, thus, smooth appearance.	Cells are cylindrical and branched. They contain multiple nuclei per cell. They have blunt ends and exhibit cross striations. They have the typical arrangement of sachromeres, thus straited appearance.

Similarities between the following:

(a). Bone and Cartilage are specialized form of connective tissue. Both are made up of cells constituted in a non-cellular matrix of non-living ground material. This gives them similar structure and they perform same function of support, movement, and protection.

(b). Both bone and blood are connective tissue.


(c). Cells of both straited and cardiac muscle are long and cylindrical. They both contract rapidly


(d). Both stratified and squamous epithelial tissue have flat layer of epithelial tissue at their outermost edge.
