Will a cow get over being paralazed from a hard birth?
Sometimes - the prognosis depends on the degree of paralysis and how long the nerve was compromised.
What are the parts of earthworms nervous system?
An earthworm has a paired brain attach to it nerve cord, that flows to its ganglia. The Clitellum ( the ring or band on the worm) is were the worm senses things. An earthworm can also not feel pain.
What is the function of ganglia?
Ganglia are clusters of nerve cells. They are mostly associated with the sympathetic division of the autonomic nervous system in vertebrates, where their functions are particularly related to the activities of the heart, glands, and involuntary muscles..
Based on their relative sizes which of the cranal nerves seem to be most highly developed in the sheep brain?
In sheep brains, the optic nerve (cranial nerve II) appears to be highly developed due to its large size relative to the other cranial nerves. This is because sheep rely heavily on their vision for survival and navigation.
Which cranial nerve used in anatomy of ear?
The vestibulocochlear nerve innervates the ear.
What is the medical term meaning Benign tumor of the peripheral nerve sheath?
A benign peripheral nerve sheath tumor is a schwannoma or neurofibroma.
What does the schwann cell form a myelin sheath around?
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.
The part of peripheral nerve tissue that helps promote regeneration of neurons is the?
The part of the peripheral nerve tissue that helps promote regeneration of neurons is the neurolemma. It refers to the thin sheath around a neural axon.
Describe the schwann cells form the myelin sheath?
Schwann cells are specialized cells in the peripheral nervous system that wrap around nerve fibers to form the myelin sheath. They provide insulation and support to the nerve fibers, which helps to speed up the conduction of nerve impulses. The myelin sheath is segmented, with small gaps called nodes of Ranvier that facilitate rapid transmission of nerve signals.
Where is location of the perineurium?
The perineurium is found in the peripheral nervous system. It is a membrane which forms a protective sheath around the fascicles (bundles of nerve fibres).
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.
What is the role of Schwann cells in forming the myelin sheath?
Schwann cells are responsible for wrapping around nerve fibers in the peripheral nervous system to form the myelin sheath. This insulating layer helps in the rapid conduction of nerve impulses along the nerve fiber. Schwann cells also provide support and maintain the health of the nerve fiber.
The Schwann cell forms a myelin sheath around the?
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.
What is neurofibrosarcoma?
Neurofibrosarcoma, also known as peripheral nerve sheath tumor, is a malignant tumor that develops in the cells surrounding these peripheral nerves. It can sometimes arise in patients with neurofibromatosis (NF1). Neurofibrosarcoma is usually found in the arms and legs and can spread extensively along nerve tissue.
What is required to maintain nerve fiber sheath?
required to maintain nerve fiber sheath
What does fatty sheath do?
The fatty sheath, or myelin sheath, surrounds and insulates nerve fibers, allowing for faster transmission of electrical signals along the nerves. It also provides support and protection for the nerve fibers.
A bundle of nerve fibers?
The bundle of the nerve fibers is a collection of the threadlike extension of the nerve cell that consists of the myelin sheath and axon in the nervous system. There are nerve fibers in the peripheral nervous system and the central nervous system.
