triple bonds

One carbon atom forms four covalent bonds with four hydrogen atoms by sharing a pair of electrons between itself and each hydrogen (H) atom.
Biomechanical mechanisms, habitat for plants and animals, participates in cycling of all materials used by living things.
The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.
Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-
1. Merkel corpuscles- detect pressure and roughness on skin.
2. Ruffini corpuscles- detect deep tension in skin, skin stretch.
3. Meissner corpuscles- perception of light touch and slip on skin.
4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.
When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.
