Question

which are functions of astrocytes? secret nerve growth factors convert blood glucose to lactate for neurons to use for fuel form blood - brain barrier regulate chemical composition of tissue fluid form myelin around axons in cns

Explanation:

Astrocytes are star - shaped glial cells in the central nervous system (CNS). They secrete nerve growth factors, convert blood glucose to lactate for neurons, help form the blood - brain barrier, and regulate the chemical composition of tissue fluid. Oligodendrocytes, not astrocytes, form myelin around axons in the CNS.

Answer:

Secrete nerve growth factors, Convert blood glucose to lactate for neurons to use for fuel, Form blood - brain barrier, Regulate chemical composition of tissue fluid
