What is the specialized cells that myelinate the fibers of neurons found in the peripheral nervous system?
The specialized cells that myelinate the fibers of neurons in the peripheral nervous system are called Schwann cells. Schwann cells wrap around the axons of neurons to form the myelin sheath, which helps to insulate and protect the nerve fibers, allowing for faster and more efficient conduction of nerve impulses.
Specialized cells that myelinate the fibers of neurons found in the pns?
Peripheral Nervous System= Oligodendrites Central Nervous System= Schwaan Cells Oligodendrites myelinate 250 times faster than Schwaan cells
What is the difference between Schwann cells and oligodendrocytes?
1) starting with the obvious; oligodendrocytes myelinate axons in the CNS whereas schwann cells myelinate axons in the PNS 2) a single oligodendrocyte is able to myelinate multiple axons whereas a schwann cell can only myelinate a single axon. 3) schwann cell myelination allows for axonal grown and regeneration where as oligodendrocytes inhibit axonal growth and regeneration. 4).... and probably a bunch more differences
Do schwann cells surround axons of neurons on the cerebrum?
No, Schwann cells do not surround axons of neurons in the cerebrum. Schwann cells are primarily found in the peripheral nervous system, where they myelinate peripheral axons. In the central nervous system, including the cerebrum, oligodendrocytes perform a similar function by myelinating axons.
Are neurotransmitters found in the myelin shealth?
No, neurotransmitters are not found in the myelin sheath. The myelin sheath is a protective covering that surrounds nerve fibers, while neurotransmitters are chemical messengers that transmit signals between neurons.
What are purkinjie fibers and in what part of the brain are they found?
Purkinje fibers are specialized neurons found in the cerebellar cortex of the brain. They play a crucial role in coordinating motor control by inhibiting other neurons, thereby regulating the timing and precision of movements. These large, multipolar cells have extensive dendritic trees, allowing them to receive a significant amount of synaptic input. Their output is primarily inhibitory, using the neurotransmitter GABA to modulate cerebellar activity.
Nervous tissue consists mainly of neurons and collagen fibers?
Actually, nervous tissue is composed of neurons, which are responsible for transmitting electrical signals, as well as glial cells that support and protect neurons. Collagen fibers are mainly found in connective tissue, not nervous tissue.
Which type of cell is NOT found in areolar tissue?
The cell type that is not found in the areolar connective tissue is chondrocytes. The three main components of connective tissue are ground substance, fibers, and cells.
Types of neurons found in mixed nerves?
Both sensory and motor neurons......
What neuron can be found in the spinal cord?
the dorsal horn of the spinal cord carries sensory or afferent nerve fibers. so basically signals get carried to the CNS.
Fibers found in connective tissue?
Elastic fibers
What are types of fibers found in fibrocartilage?
collagen fibers
