Samantha Hutchins 10/27/15 Vitamin D Deficiency 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.

During a Muscle Contraction The muscle fiber is in a resting state. The resting state is slightly negative inside and slightly positive outside. It has to be in this state in order to receive a message. First the brain sends a message to the muscle using a neuron then reaches the axon terminal of the neuron. Calcium gates then open on the axon terminal allowing calcium to rush in. Ach release from axon terminals‚ diffuses across the synaptic clef and binds to (receptors) on motor end plate. Then

Bone tissue continuously renews itself throughout life as a result of a variety of stimuli by the process of bone remodeling‚ in which old bone is replaced by new bone in order to preserve bone strength and mineral stability. It requires a particular balance between bone deposition and resorption‚ by the combined action of osteoblasts and osteoclasts‚ respectively. This process prevents the accumulation of bone micro-damage‚ removing injured bone and reshaping bones in response to use and disuse
