Question

brain anatomy

• the brain is made up of
• ~86 to ~100 billion nerve cells (called __________) and
• ten times as many ________ cells (called ________)
• physical support for ________ and ________
• supply ________ (________ & raw materials for repair)
• ________ & clear up debris (________)

Explanation:

These are key terms related to brain anatomy, focusing on the two main cell types in the brain and the functions of the support cells. Neurons are the primary nerve cells, while glial cells (specifically astrocytes, oligodendrocytes, microglia) provide support, nutrients, and cleanup functions.

Answer:

• ~86 to ~100 billion nerve cells (called neurons) and
• Ten times as many support cells (called glial cells)
• Physical support for neurons and blood vessels
• Supply nutrients (oxygen & raw materials for repair)
• Remove waste & clear up debris (microglial cells)
