Which muscle is most typically used to give injection in the arm-

Correct option is C

Sol. The deltoid muscle is most commonly used for injections in the arm. It is located at the upper part of the arm and is easily accessible, making it ideal for intramuscular injections.
Explanation of each option:
· (a) Biceps – The biceps are not commonly used for injections as they are smaller muscles compared to the deltoid, making it difficult to administer a proper injection.
· (b) Triceps – While it is a larger muscle, the triceps is not generally used for injections because of its location and less accessible nature compared to the deltoid.
· (c) Deltoid – Correct answer. The deltoid is the most commonly used muscle for injections due to its size and easy access. It's located on the upper arm and is a standard site for intramuscular injections.
· (d) Brachialis – This muscle is located underneath the biceps and is not typically used for injections.
