GENERAL HISTOLOGY

Detailed explanation-1: -L5 spinal nerve provides sensation to the outer side of your lower leg, the upper part of your foot and the space between your first and second toe. This nerve also controls hip, knee, foot and toe movements.

Detailed explanation-2: -Lumbar region The lumbar spinal cord is the lower area of the back. Nerve roots coming from the spinal cord in the lumbar spine control the legs.

Detailed explanation-3: -The lumbar spine is the lower back that begins below the last thoracic vertebra (T12) and ends at the top of the sacral spine, or sacrum (S1). Most people have 5 lumbar levels (L1-L5), although it is not unusual to have 6. Each lumbar spinal level is numbered from top to bottom-L1 through L5, or L6.

Detailed explanation-4: -L5-S1 helps transfer loads from the spine into the pelvis and legs. The L5-S1 motion segment has distinctive anatomy and receives a higher degree of mechanical stress and loads compared to the segments above.

Detailed explanation-5: -The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles. The nerves also carry electrical signals back to the brain that allow you to feel sensations.
