Central Nervous System

Utak mo puta

Planning, processing, coordination, and excretion

What is the main function of the Central Nervous System

Neurons or Brain cells

The basic unit of the Central Nervous System (put both terms)

Dendrites

ANO YUNG A GAGO

Cell body

WEH DI NGA B NAMAN ANO YUNG B

Supporting Cells or Glial Cells

Kala mo talaga may bitaw e, dehins mo alam ang C g bounce kanalang ARAY KUOH!!!

Axon

Ano naman yung D bro bro

Dendrites

Receive impulses towards the cell body

Axon

Carry impulses away from the cell body

Neuron

Ano yung A SBAPN

Axon

Dehins mo alam yung B g, mabuting mag ekoms kanalang lakas mo!

Microglia

Ano yung C btw kumain kana?

Astrocyte

Ano naman ung D pookie bear:3

Presynaptic and Postsynaptic terminal

Dikona alam icacaption ano yung E, dalawa sila

Oligodendrocytes

Hulaan mo kung ano pinapahanap ko, clue sya angletter na lalabas sa lahat subjects ko this semester hehe

Supporting Cells or Glial cells

● Provide nutrition, structure, and immune protection

● Found in both brain and spinal cord

Brain and Spinal Cord

Saan nahahanap ang supporting cells o glial cells

Astrocytes

Support – they hold neurons together forming a framework in the brain

○ Nutrition – they act as a bridge between neurons and blood vessels helping absorb nutrients.

■ Blood vessels carry nutrients - ______ absorb and deliver them to neurons

processes

Ano tawag sa mga galamay ng astrocytes

Astrocytes

TANGINA MO ANDALI NATO EWAN KONALANG TALAGA

Near Capillaries

Saan nahahanap ang astrocytes

Microglia

Ano toh? no hindi sya stain sa brief ko

Microglia

● Functions: ○ Immune cells of the CNS ● Phagocytic – eats bacteria, viruses, and dead cells sa loob ng CNS, activated during infection, inflammation, or injury

Astrocyte

Long and Thin processes

Microglia

Short and Thick Processes

Phagocytic

Ano tawag sa trait ng Microglia na kumakain sila ng bacteria, viruses, and dead cells sa loob ng CNS, activated during infection, inflammation, or injury

Oligodendrocytes

Wrap myelin sheath around multiple axons ● Myelin = plastic-like cover → speeds up impulse conduction

Schwann Cells

■ Produce myelin sheath outside

● Wrap myelin sheath around one axon only
