Biology: How we communicate, endocrine, and nervous system

What challenged do type 1 diabetics face

pancreas fails to produce insulin = high blood sugar levels

What challenges do type 2 diabetics face

body’s cells stop responding to insulin properly (often life style related)

Neurotransmitters

chemical messengers stored in synaptic vesicles at the axon terminals of neurons that carry signals across synaptic gaps to target cells like muscles, glands, or other neurons.

Hormones

recreated by glands, travel through bloodstream to regulate mood, growth, and reproduction

Medulla

regulates basic physiological processes like heartbeat and breathing

Cerebellum

controls posture and balance

Hypothalamus

controls keeping body in homeostasis

Cerebrum

controls qualities considered to be of the mind like learning, memory, motivation, and emotion

Sensory

senses of vision, hearing, smell, taste, and touch

What lobe of the brain is sensory located

parietal, occipital, and temporal lobe

Motor

voluntary movements

What lobe of the brain is motor located

frontal lobe

Association

judgement, analysis, learning, creativity

What lobe is Association is located

frontal lobe and parts of parietal, occipital and temporal

Endocrine

• chemical signals

• hormones

• slower

• long lasting

• blood stream

growth and development

Nervous

• electrical impulses

• action potentials

• fast

• usually short

• nervous pathways

Hypothalamus

maintains homeostasis

• in the brain

Cell Body

organelles

Dendrites

• receives signals

• transmits them toward the cell body

Axon

conducts nerve impulses away from the body

Myelin Sheath

fatty neuroglia cells wrapped around axons, speeding up signal transmission
