They are less specialised.
-
Voluntarily
-
Unbranching
-
Unseparability
-
Indefatigability
D
Correct answer
Explanation
They do not get fatigued out.
-
They are thick and straight.
-
They occur single and separately.
-
They are formed from collagen protein.
-
They are digested by trypsin.
C
Correct answer
Explanation
They are white and are formed by collagen protein.
-
They are inelastic and unbranched.
-
They are made up of collagen protein.
-
They are digested by trypsin.
-
They occur in bundles.
D
Correct answer
Explanation
They occur in single form.
-
They have only one nucleus.
-
They have sarcolemma.
-
They have numeorus mitochondria.
-
They have stored glycogen granules.
B
Correct answer
Explanation
They do not possess sarcolemme. They possess only plasma membrane.
-
Muscles
-
Kidney
-
Heart
-
Nerves
A
Correct answer
Explanation
The study of muscles is called myology.
-
Because the muscle cells respire aerobically.
-
Because of anaerobic respiration which takes place in the muscles.
-
Because we breath more hard to fulfill the supply of oxygen.
-
None of these
B
Correct answer
Explanation
Yes, anaerobic respiration takes place in our muscles to fulfill the supply of oxygen. Lactic acid is released resulting in its accumulation which causes cramps. Hot water bath/massage helps in relieving pain.
-
troponin
-
tropomyosin
-
actin
-
myosin
D
Correct answer
Explanation
Myosin protein is found in dark band.
B
Correct answer
Explanation
The masseter muscle, located in the jaw, is considered the strongest muscle in the human body based on its ability to exert force during chewing.
-
Due to formation of lactic acid.
-
Due to evolution of high concentration of CO2.
-
Due to formation of ethanol.
-
Due to complete absence of oxygen in muscles.
A
Correct answer
Explanation
Due to formation of lactic acid, muscle cramps are caused after heavy exercise.
-
urethra contracts
-
urethra relaxes
-
ureter contracts
-
ureter relaxes
B
Correct answer
Explanation
Micturition is possible only if the muscles of urinary bladder contract and urethra relaxes.
-
Areolar tissue
-
Adipose tissue
-
Dense connective tissue
-
Muscle tissues
-
Neural tissues
C
Correct answer
Explanation
Fibres and fibroblasts are packed compactly in dense connective tissue. Tendons are dense regular tissues that attach skeletal muscle to bones and ligaments attach bone to another bone. Collagen is the dense irregular connective tissue present in the skin.
-
203
-
308
-
200
-
400
-
None of these
D
Correct answer
Explanation
The human body contains over 600 skeletal muscles. Since 400 is the closest option provided and the others are significantly lower, it is the intended answer in this context, though the exact number is higher.
-
muscular
-
epithelial
-
nervous
-
connective
A
Correct answer
Explanation
Skeletal muscle is the most abundant of the human body's tissues.
D
Correct answer
Explanation
The gluteus maximus or buttock muscle is the biggest of the 639 named muscles in the human body.
