Which muscle condition is characterized by a resistance to stretch and may occur following brain injury?

A. Muscular dystrophy
B. Spasticity
C. Hyperthermia
D. Myasthenia gravis



Answer :

Final answer:

Spasticity is a muscle condition involving resistance to stretch following brain injury. It contrasts with myasthenia gravis and muscular dystrophy.


Explanation:

Spasticity:

Spasticity is the muscle condition characterized by resistance to stretch and can occur following brain injury. It involves increased muscle tone, stiffness, and involuntary muscle contractions. A common example of spasticity is seen in conditions like cerebral palsy or after a stroke.

Myasthenia gravis:

Myasthenia gravis, on the other hand, is a neuromuscular disease characterized by muscle weakness and fatigue, often due to antibodies attacking acetylcholine receptors at the neuromuscular junction.

Muscular dystrophy:

Muscular dystrophy is a group of genetic disorders causing progressive muscle weakness and degeneration. It is different from spasticity and myasthenia gravis.
