An acute, focal neurologic deficit is the hallmark of stroke. Major strokes involve both motor and sensory components. Symptoms may be sudden and maximal at onset (embolic) or intermittent and stuttering (thrombotic). Findings in stroke syndromes depend on the territory of brain suffering infarction.
The primary mover during the seated or lying leg extension exercise is a group of four muscle heads on the front of the thigh, collectively referred to as the quadriceps. The largest muscle head is the rectus femoris, which sits in the center of the front thigh.
Muscle Strains in the Thigh. A muscle strain (muscle pull or tear) is a common injury, particularly among people who participate in sports. The thigh has three sets of strong muscles: the hamstring muscles in the back of the thigh, the quadriceps muscles in the front, and the adductor muscles on the inside. The quadriceps muscles and hamstring muscles work together to straighten (extend) and bend (flex) the leg. The adductor muscles pull the legs together.
