Which of the following is a correct match for disease and its symptoms?
- Arthritis - Inflamed joints
Tetany - high Ca2+ level causing rapid spasms
- Myasthenia gravis - Genetic disorder resulting in weakening and paralysis of skeletal muscle
- Muscular dystrophy - An autoimmune disorder causing progressive degeneration of skeletal muscle
The Correct Option is A
Solution and Explanation
Tetany - Tetany is a symptom characterized by the involuntary contraction of muscles that usually results from low calcium levels in the blood
(i.e., hypocalcemia).
Myasthenia gravis - An autoimmune disorder in which antibodies destroy the communication between nerves and muscle, resulting in
weakness of the skeletal muscles.
Muscular dystrophy - Genetic disorder that causes progressive weakness and loss of muscle mass.

Locomotion and Movement
Locomotion
The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.
Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.

Movement
Movement is generally described as a state of changing the position from rest to motion or vice-versa. Movement can be both voluntary movement and involuntary movement. Movement helps an organism perform essential functions, such as pumping blood to the different parts of the body, etc.
