The largest peripheral nerve in the human body is the sciatic nerve. It originates from the lower back, branching from the lumbar and sacral plexus, and extends down the back of each leg. The sciatic nerve is responsible for transmitting signals to and from the legs and feet, playing a crucial role in movement and sensation. Its size and length make it the most significant nerve in the peripheral nervous system.
What else can I help you with?
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
Which nerve belongs to the peripheral nervous system A. Sciatic nerve B. Vagus nerve C. Optic nerve D. Trigeminal nerve?
sciatic
Repair of nerve fibers differ in the peripheral nervous system and the central nervous system?
How does the repair of nerve fibers differ in the peripheral nervous system and the central nervous system? How does the repair of nerve fibers differ in the peripheral nervous system and the central nervous system? How does the repair of nerve fibers differ in the peripheral nervous system and the central nervous system? How does the repair of nerve fibers differ in the peripheral nervous system and the central nervous system? We can help our nervous systems by improving our reflexes
Do all nerve cells have a neurilemma?
No, not all nerve cells have a neurilemma. The neurilemma is a part of peripheral nerve fibers but is not present in the central nervous system. It is a layer of Schwann cells that surround and protect the axon of peripheral nerves.
Are the nodes of ranvier found at a regular interval only on myelinated peripheral nerve fibers?
No, the nodes of Ranvier are found at regular intervals on both myelinated central and peripheral nerve fibers. They are gaps in the myelin sheath where the axon is exposed, allowing for the propagation of action potentials along the nerve fiber.
List the reasons for performing a peripheral nerve functions assessment?
A peripheral nerve function test is performed to test the nerve function in the peripheral nerve. This test is often performed to when there is pain or weakness in the limbs.
Does the peripheral nervous system have sensory nerve cells and motor nerve cells.?
Yes, the peripheral nervous system has both sensory and motor nerve cells
What is the medical term meaning Benign tumor of the peripheral nerve sheath?
A benign peripheral nerve sheath tumor is a schwannoma or neurofibroma.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
Providing a pathway for the transmission of nerve impulses is the responsibility of the?
peripheral nerve system
What is the cost of peripheral nerve surgery?
there is no such thing
What fibers are the most rapid nerve impulses conducted on?
These are nerves in animals. They include central and peripheral; peripheral include somatic and autonomic.
What has the author Elfriede Sluga written?
Elfriede Sluga has written: 'Polyneuropathien: Typen und Differenzierung' -- subject(s): Classification, Diseases, Pathology, Peripheral Nerve Diseases, Peripheral Nerves, Peripheral nerve diseases
Does the peripheral nervous system have sensory nerve cells and motor nerve cells?
False
What does pnbs stand for?
