Endocrine System

hormones, slow

Nervous System

neurotransmitters, fast - sensory (sensing changes)/integrative (makes change)/motor (react to changes - muscular/grandular)

Central Nervous System

Brain/Spinal Cord - sensory receptors, sends motor neurons to muscles/glands (PNS), goes to thalamus, Tuj1/Cleaved-CaspaseDAPI - measures cell death

Peripheral Nervous System

cranial (originated from brain)/spinal (originate from spinal cord)/ganglia (inside PNS) - sensory (afferent - to CNS) - motor (efferent - from CNS out) - ganglia (connected to PNS)

Peripheral Nervous System Prop.

somatic (voluntary - skin/sense receptors) - autonomic (involuntary/visceral - organs sympathetic - emergency (fight or flight - dilation of eye - Nicotinic/Muscarinic/Adrenergic) /parasympathetic - homeostasis (rest or digest - constriction of eye - Nicotinic/Muscarinic))

Enteric Nervous System

involuntary, associated with gastrointestinal GI tract, autonomic, capable of carrying reflexes + in absence of CNS input become integrating center (makes change), myenteric plexus (controls gut mobility)

Nervous System Org.

sensory (PNS) -afferent→ interneuron (CNS) —> motor -efferent→ glandular/muscular
