The point of attachment of the nerve to the muscle is called a _ junction.
Correct answer: A. Neuro-muscular
- A. Neuro-muscular
- B. Mechanical
- C. Chemical
- D. Synaptic
Explanation
The correct option is a) Neuro-muscular junction.Let's explain each option individually:The neuro-muscular junction is the point of connection between a nerve and a muscle fiber. It is a specialized synapse where the nerve ending, known as the motor neuron terminal, comes into close proximity with the muscle fiber. The motor neuron releases a neurotransmitter called acetylcholine, which binds to receptors on the muscle fiber, initiating muscle contraction.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
