Anatomy
Found in the brain, spinal cord, and nerves.
Nervous Tissue
Transmits nerve impulses away from the cell body to the synapse
axon

Metabolism
Thyroid
A
Asymmetry
Which part of the brain is responsible for sensory processing and relaying information?
Thalamus
Includes cardiac, smooth, and skeletal muscle.
Muscular Tissue
Receive signals from other neurons.
Dendrites
Neck
Regulates blood calcium
Parathyroid
B
Border irregularity
Which part of the brain regulates emotions and memory?
Limbic System
Lines GI tract organs and hollow organs; found on the skin surface (epidermis).
Epithelial Tissue
Form the myelin sheath, which insulates axons.
Schwann cells
Brain
Regulates sleep cycle (melatonin)
Pineal
C
Color variation
What do coughing and sneezing have in common?
Both remove irritants from the respiratory tract.
Includes fat, bone, blood, and tendons.
Connective Tissue
Brain & spinal cord.
Central Nervous System (CNS)
On top of kidneys
Produces stress hormones (cortisol, adrenaline)
Adrenal

Diameter > 6mm
Why does nasal breathing stop particles better than mouth breathing?
The nasal cavity contains cilia and mucus, which filter out debris earlier than the mouth.
Which organ system defends against pathogens and returns fluids to the blood?
Lymphatic System
Controls voluntary movements.
Involuntary functions.
Somatic Nervous System
Autonomic Nervous System
In front of the heart
Produces T-cells for immunity
Thymus
E
Evolving (changes over time)
Four Lobes of the Cerebral Cortex:
Frontal: Reasoning, movement, problem-solving.
Parietal: Sensory processing (touch, pain, temperature).
Temporal: Hearing, memory, language.
Occipital: Vision processing.
