Bio 17 – Nervous & Endocrine Systems

Atoms and Ions

Plasma Membranes

Transport

Resting Potential Sodium/Potassium Pump Potassium Channels (K+) Sodium Channels (Na+)

Action Potential

How Neurons Communicate… IPSP = Inhibitory Postsynaptic Potential EPSP = Inhibitory Postsynaptic Potential

Important for sleep, mood, learning; HIGH = Schizophrenia; LOW = Parkinson’s High Runner’s high INCREASED DOPAMINE Aggression; Serial killers low levels; important for sleep and low levels assoc with depression Runner’s High = DECREASED GABA

Drug Effects Morphine SSRI – Lexapro; Prozac Curare

The Brain = Many Neurons Glial Cells

The Brainstem * The Medulla Oblongata and the Pons controls breathing, heart rate, digestion The Cerebellum controls coordination of movement and balance (Karate; Dance. Separate Section of the brain)

Stairs…

The Midbrain * The Midbrain receives, integrates, and projects sensory information to the forebrain

Hypothalamus Thalamus conducts information to specific areas of cerebrum _____________ produces hormones and regulates body temperature, hunger, thirst, sexual response, circadian rhythms Hypothalamus

* Cerebrum with cortex and corpus callosum higher thinking
