SIGNALS ...requires direct cell to cell contact Paracrine
Neuronal Hypothalamus Pineal Gland Pituitary Gland Thymus Thyroid Gland Pancreas Adrenal Glands Testis Ovaries Hormone(s) Target melatonin
estrogen/progesterone pituitary gland
ovum Function... ...rapid response to stimuli Nervous System CNS
Central Nervous System PNS
Peripheral Nervous System Sensory motor somatic autonomic sympathetic parasympathetic brain & spinal cord
protected by: meninges
blood brain barrier ...detects exernal stimuli and internal conditions Flow of Information... Reflexes... CELL TYPES Glial Cells Neurons support and assist neurons
two types: Schwann Cells
astrocytes transmit information rapidly by electric and chemical signals
Flow of information: dendrite > cell body > axon hillock > axon > synaptic terminals > synapse > target cell Action potential... ...nerve impulse >> electrical wave that travels through a neuron
caused by the movement of ions sodium ions (Na+)
potassium ions (K+)
