The optic nerve is the nerve that connects the eye to the brain and carries the impulses formed by the retina to the visual cortex of the brain. The choroid is a thin vascular layer between the sclera and the retina that supplies blood to the retina and conducts arteries and nerves to other structures in the eye.
A muscle pull (or strain) occurs when you twist, pull, or tear your muscle or tendon, the strong elastic cord that connects your muscle to the bone. As we age we are more susceptible to muscle pulls. However, you risk a pull if you donât warm up properly before you exercise and stretch a muscle past its limit, train longer than what your body can handle, or if you push a past muscle injury too far before the muscle has had adequate time to heal.
Another cue you are experiencing pain and not muscle soreness is if you begin to feel symptoms in a part of your body not being exercised.
