State the functions of:  1. Smooth muscles

Strenuous exercise produces Lactic acid in muscles.

A) skeletal muscles

B) Striated muscles

C) 1 – a, 2 – b, 3 – c

Smooth muscles are also known as nonstriated, visceral or involuntary muscles.  Structure:  1. These muscles are present in the form of sheets or layers.  2. Each muscle cell is spindle shaped or fusiform.  3....

Smooth Muscles Skeletal Muscles 1. These muscles are found in the walls of visceral organs and blood vessels. These muscles are found attached to the bone. 2. Each muscle cell is spindle shaped or fusiform and...

Smooth muscles are also known as non- striated, visceral or involuntary muscles.  Structure:  1. These muscles are present in the form of sheets or layers.  2. Each muscle cell is spindle shaped or fusiform.  3....

Muscles of the cardiac tissue show characteristics of both striated and nonstriated muscle fibres.  Structure:  1. Sarcolemma is not distinct.  2. Uninucleate muscle fibres appear to be multinucleate.  3. Adjacent muscle fibres join together to...

(1) f(x) = \(\frac{x}{1-x^3}\)  f(-x) = \(\frac{-x}{1-(-x)^3}\)  = \(\frac{-x}{1+x^3}\) ≠ -f(x) or f(x) ∴ f(x) is neither even nor odd function. (2) f(x) = \(\frac{x^2}{1+x}\)  ∴ f(-x) = \(\frac{(-x^2)}{1+(-x)}\)  = \(\frac{x^2}{1-x}\) ≠ -f(x) or f(x). (3) f(x) = x-|x| ∴ f(-x) = -x-|-x| = -x-|x| = -(x+|x|) ≠ -f(x)...

i. Muscular dystrophy:  1. It is a gradual wasting disease affecting various groups of muscles.  2. It is a genetic disorder.  3. Usually the voluntary skeletal muscles are weakened whereas internal muscles such...
