Motor neurons are involved in the skeletal muscle contractions in vertebrates, as the process is a synaptic one. These occur due to a conscious effort by the brain, from which these signals originate. In some reflexes, the signal originates from the spinal cord.
Answer:
The difference between the microfilaments, intermediate filaments, and microtubules are stated below.
Explanation:
- They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
- They have a diameter of about 7 nanometre.
- They help in cellular movement.
- They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
- They have a diameter which ranges from 8 nanometre to 10 nanometre.
- They have structural function and are required to maintain the cell shape and organelle position.
- They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
- They have a diameter of about 25 nanometre.
- They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
