The glial cells that form myelin around axons in the peripheral nervous system.

Schwann cells

The four classic signs of inflammation are collectively known as the cardinal signs.

Redness, heat, swelling, and pain

30

The brain lobe primarily associated with hearing and memory. 

Temporal lobe

30
