neurobiology and pharmacotherapy

mental health

what are the functions of the brain?

maintenance of homeostasis

regulation of ANS and hormones

control of biological drives and behavior

circadian rhythms

memory

the frontal lobe (emotional brain) is responsible for what?

emotional control and regulation

social and emotional reasoning

emotional processing

personalitu and mood

what does core do?

regulates internal organs and vital functions

what does the hypothalamus do?

basic drives and link between thought and emotion and function of internal organ s

what does the brainstem do?

processing center for sensory information

the ANS is part of the

peripheral nervous system and is compromised of symphathetic and parasympathetic nervous systems

the PNS is responsible for regulating

involuntary functions such as HR, digestions and respirations, and is controlled by the hypothalamus

what is sympathetic ?

fight or flights response, preparing the body for action in stressful situations

what is parasympathetic?

regulating involuntary functions such as HR, digestion and respirations, rest and digest

what is the role of brainstem in ANS?

regulating autonomic functions with nuclei in the brainstem controlling the parasymphatethic preganglionic. neurons

what are neurons composed of?

cell body

axons

dendrites

the neurons are the…

info messengers of the brain and this is how the brain communicates

the neurons respond to?

electrical and chemical signals received by there dendrites and cell body

the neurons conduct?

electrical impulses called action potentials down their axons

the neurons release?

chemical messengers called NT into the synapse

a cell body (soma)?

contains the nucleus and controls the cells activities and houses genetic material

axons?

send messengers way from the cell body and transmit electrical impulses which act as insulator to help accelerate nerve impulses

dendrites?

act like antennae to receive signals from other neurons which are then passed to the cell body

what is a synapse?

the junction where a neuron communicates with another cell

what is a NT?

chemical messengers that transmit impulses across a synapse

what are the NT function?

function in human emotions and behaviors and are the targets for many psychotropic medications

how the NT communicate?

when a electrical signal in the neurons axon triggers the release of chemical NT across a synapse to the dendrite of another neuron

the axon is

a neuron that conducts electrical impulses away from the cell body towards the neuron

synapse is the

dendrite is the

reuptake?
