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
Does the PNS lack endoneurium?
No, the peripheral nervous system (PNS) does contain endoneurium. Endoneurium is the connective tissue that surrounds individual nerve fibers within a nerve bundle. It provides support and protection to the nerve fibers in the PNS.
What has a nervous system but no brain 1 earthworm 2 hydra 3 cockroach 4 amoeba?
Earthworms and cockroaches have nervous systems but no brain. Hydras have a nervous system consisting of a nerve net but lack a centralized brain. Amoebas do not have a nervous system or a brain.
What are the characteristics of fatigue?
Fatigue is characterized by a profound lack of energy, feelings of muscle weakness, and slowed movements or central nervous system reactions. Fatigue can also trigger serious mental exhaustion.

inagition
What does fatigue feel like?
fatigue is characterized by a profound lack of energy, feelings of muscle weakness, and slowed movements or central nervous system reactions. Fatigue can also trigger serious mental exhaustion.
What is non-myelinated nerve fiber?
a nerve fiber that lacks the fatty myelin insulating sheath. Such fibers form the gray matter of the nervous system, as distinguished from the white matter of myelinated fibers. Also called nonmedullated nerve fiber.
What are the signs of fatique?
Fatigue symptoms include tiredness or exhaustion resulting in the more extreme cases in a loss of consciousness or in more moderate versions a need to rest due to general lack of energy or strength.
What are medullated and non- medullated nerve fibres?
Depending on the number of sheaths ,nerve fibres are of two types :-Myelinated (Medullated) Nerve Fibre.Nonmyelinated (NonMedullated) Nerve Fibre.Myelinated (Medullated) Nerve Fibre.:-are those nerve fibres which are covered by two sheaths ,myelin & neurolemma.Nonmyelinated (NonMedullated) Nerve Fibre.:-these nerve fibres are devoid of myelin sheath .However,neurolemma is present.
Which animals does not have nervous system?
Sponges do not have a nervous system. They are simple aquatic animals that lack organs and have a decentralized network of cells for coordinating their activities.
What do animals with nerve nets have?
Animals with nerve nets possess a decentralized network of interconnected nerve cells, which allows them to respond to stimuli from their environment without a centralized brain. This simple nervous system is typically found in organisms like cnidarians, including jellyfish and sea anemones. Nerve nets enable these animals to coordinate basic movements and reflexes, facilitating functions such as feeding and locomotion. Their lack of a central nervous system limits complex behaviors but allows for effective responses to stimuli.
