For muscle-building anabolic steroids we can say that:
-
They are relatively risk free to use
-
They have side effects that outweigh their benefits
-
They increase muscular strength and endurance
-
Both (b) and (c)
Which of the following ions are necessary in the chemical events of the muscle contraction?

Sodium and Potassium
-
Sodium and Magnesium

Calcium and Magnesium

Cori's cycle operates in
-
Liver
-
Muscles
-
Blood
-
Both A and B
The Cori cycle (lactic acid cycle), refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is metabolized back to lactate.
Polio disease affects

Skeleton and muscular system
Polio is a viral disease, which affects the spinal cord causing muscle weakness and paralysis. The polio virus enters the body through the mouth, usually from hands contaminated with the stool of an infected person.
A sheath of connective tissue that wraps around several muscle bundles forming a muscle is called
-
Sarcolemma
-
Fascicle
-
Endomysium
-
Fascia
Which muscles move the fore limb?
-
Brachialis
-
Latis simus dorsi
-
Dorsal scapularis
-
Triceps brachii
The brachialis is a muscle in the upper arm that flexes the elbow joint.
The Latissimus dorsi is the larger, flat, dorsolateral muscle on the trunk, posterior to the arm.
The dorsal scapular is the nerve that is the right brachial plexus with its short branches, viewed from in front.
Triceps brachii is that large muscle on the back of the upper limb and is principally responsible for extension of the elbow joint (straightening of the arm).
Therefore, the correct answer is option A.
The cycle of reactions by which muscle lactic acid is transformed to muscle glycogen is known as
-
Glycolactic cycle
-
Glycolysis
-
Cori cycle
-
Krebs cycle
The Cori cycle (also known as lactic acid cycle), refers to the metabolic pathway, in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is metabolised back to lactate.
One of the following is a set of antagonistic muscles. Select the wrong set.
-
Fexor, Relaxor
-
Abductor, Adductor
-
Pronator, Supinator
-
Elevator, Depressor
Flexation of thigh, knee and their rotation is facilatated by
-
Biceps muscle
-
Triceps muscle
-
Sartorius muscles
-
Shank
The sartorius muscle is the longest superficial muscle in the interior compartment of the human body. It is a two joint muscle that moves both hip and knee joint. It forms the lateral boundary of the femoral triangle and covers the abductor canal. It flexes the hip and knees and helps in the lateral rotation and thigh abduction. These all are necessary for the crossed leg position. So, the correct option is C.
