Regarding Muscles Vitamin D deficiency has been tied to mainly bone pathologies. Recent research shows that the effects of Vitamin D span further than just affecting bones and particularly cause muscle weakness. Vitamin D is responsible for aiding in the absorption of other minerals‚ such as calcium. Calcium is a key ligand in muscle contractions‚ thus‚ Vitamin D indirectly can effect muscle contractions.

The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins

muscular and skeletal systems play a very important role in the body. They help each other perform functions for the entire body. The muscular system and the skeletal system are the basis of the body structure. The muscular system generally produces movement. The skeletal basically provides the necessary support for these systems to work together. The skeletal system has many organs. Some organs include bones‚ cartilage‚ and ligaments. Teeth are also considered a part of the skeletal system but
