The major plexuses of the spinal cord?
The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
A fall or improper administration of an injection to the buttocks may injure a nerve of this plexus?
sacral plexus
Which plexus gives rise to the sciatic nerve?
The sacral plexus gives rise to the sciatic nerve. It is formed by the ventral rami of spinal nerves L4-S4 and is the largest nerve in the body.
Which plexus contains the foot and the leg?
The lumbar plexus contains nerve fibers that innervate the leg, and the sacral plexus contains nerve fibers that innervate the foot. The lumbar plexus arises from the lower spinal cord levels, while the sacral plexus arises from the sacral spinal cord levels.
What is the Network of spinal nerves that supplies the pelvis and legs?
The network of spinal nerves that supplies the pelvis and legs is known as the lumbosacral plexus. It is formed by the lower lumbar and sacral spinal nerves and gives rise to various nerves that innervate the lower extremities, including the sciatic nerve, femoral nerve, and obturator nerve. These nerves play a crucial role in motor and sensory functions of the pelvis and legs.
