Neurons
Create currents in the brain that travel down the axon
1 of 23
Nerve
Billions of neurons make them
2 of 23
Synapses
Gaps between neurons
3 of 23
Motor neurons
Short dendrites and long axons
4 of 23
Sensory neurons
Long dendrites and short axons
5 of 23
Relay neurons
short dendrites and long or short axons
6 of 23
Action potentials
Electrical charges sent down the axon
7 of 23
Saltatory conduction
Jumping of electrical through the Nodes of Ranvier
8 of 23
Synaptic transmission
Synaptic gap --> Dendrites --> Axon--> Nodes of ranvier--> Axon terminal--> Synaptic vesicles--> Neurotransmitters--> synaptic gap--> post synaptic receptors--> dendrites
9 of 23
Hypothalamus
Link between the endocrine system and the nervous system. Releases and inhibits hormones & stops and starts other hormones
10 of 23
Pituitary gland
'Master gland'. Regulates the functions of the endocrine glands. Sends signals to release and inhibit hormone production
11 of 23
Thyroid
In the throat. Regulates metabolism through the hormone thyroxine
12 of 23
Thymus
Under the thyroid. Only active until puberty. Hormone = thymosin. Aids the immune system
13 of 23
Adrenal glands
Above the kidneys. Produces hormones that are vital for life- cortisol
14 of 23
Pancreas
Above the adrenal glands. Maintains blood glucose levels in the body. Hormone = insulin and glucagon
15 of 23
Ovaries
oestrogen & progesterone. Breast development, fat distribution on hips, legs & breasts and development of female reproductive system
16 of 23
Testes
Testosterone. Maintains healthy development of male sex organs, growth of facial & body hair, lowering of voice, increase in height & muscles & growth of adam's apple
17 of 23
Two parts of the pituitary gland
Anterior lobe and posterior lobe
18 of 23
Adrenal gland parts
Outer = adrenal cortex & Inner = adrenal medulla
19 of 23
Acute stress
SAM Pathway (Sympathetic Adrenal Medullary) = fight or flight
20 of 23
Chronic stress
HPA Pathway (Hypothalamic Pituitary Adrenal) = no fight or flight
21 of 23
SAM Pathway
Stressor --> Hypothalamus--> Sympathetic branch--> Adrenal Medulla--> Adrenaline & Noradrenaline--> Heart, breathing rates increase
22 of 23
HPA Pathway
Stressor--> Hypothalamus--> Pituitary gland--> ACTH--> Adrenal cortex--> Cortisol
