The Brain
100

This part of the the neuron can reach lengths of over 2 feet long

axons

100

The chambers on top of the heart

atrium

100

This cell loves to phagocytose, which in Greek means "eat"

Macrophage

100

This disease is caused by a blockage of a coronary artery

myocardial infarction (heart attack)

100

This brain structure connects the brain to the spinal cord

The brain stem (or medulla)

200

bundles of neurons in the peripheral nervous system are known as these

nerves

200

the chambers on bottom of the heart

ventricles

200

This subtype of T cell is a killer

Cytotoxic or killer T cell

200

Acquired Immunodeficiency Virus (AIDs) is caused by this virus

HIV

200

This "little brain" structure helps you balance and coordinate movement

the cerebellum

300

The part of the neuron that receives neurotransmitter signals

the dendrite

300

this is the only vein with oxygenated blood

pulmonary vein

300

This cell will produce antibodies

The B Cell (or plasma cell)

300

This disease is caused by defects in hemotopoetic stem cell differentiation causing the loss of white blood cells

Leukemia

300

Famous patient "HM" couldn't store long term memories because of the damage to this

Hippocampus

400

The resting potential (in millivolts)

-70 mV

400

this prevents blood from flowing backwards into the right atrium

the tricuspid valve

400

If you cut your finger, this cell will show up and dump out granules of histamine.

the mast cell

400

This disease is caused by damage to the facial nerve (the 7th cranial nerve).

Bells Palsy


400

This superficial layer of the brain has gray matter and is associated with information processing

the cerebral cortex

500

This ion rushes into the cell during depolarization

Sodium

500

This node initiates the heartbeat and is also known as the "pacemaker" of the heart

sinoatrial node

500

This protein complex displays antigens on the surface of human cells

Major Histocompatibility Complex (MHC)

500

This nervous system auto-immune disease is caused when immune cells attack and degrade the myelin sheath.

Multiple Sclerosis

500

This part of the brain stem controls heart rate and breathing

the medulla
