Difference between neurons,astrocytes and oligodendrocytes

Answer 1

║⊕ANSWER⊕║

WHAT ARE NEURONS?

• A specialized cell transmitting nerve impulses; a nerve cell.

FUNCTIONS OF NEURONS

• A neuron (also known as nerve cell) is an electrically excitable cell that takes up, processes and transmits information through electrical and chemical signals.
• It is one of the basic elements of the nervous system.
• In order that a human being can react to his environment, neurons transport stimuli.

WHAT ARE ASTROCYTES?

• A star-shaped glial cell of the central nervous system.

FUNCTIONS OF ASTROCYTES

• Astrocytes get their name because they are "star-shaped".
• They are the most abundant glial cells in the brain that are closely associated with neuronal synapses.
• They regulate the transmission of electrical impulses within the brain.
• Metabolic support: They provide neurons with nutrients such as lactate.

WHAT ARE OLIGODENDROCYTES?

• Oligodendrocytes are a type of large glial cell found in the central nervous system.

FUNCTIONS OF OLIGODENDROCYTES

• Oligodendrocytes produce the myelin sheath insulating neuronal axons (analogous to Schwann cells in the peripheral nervous system), although some oligodendrocytes (called satellite oligodendrocytes) are not involved in myelination.
