The Brain, Psych test Flashcards
whats psychology
Psychology is the scientific study of behaviours and mental processes.
whats psychiatry
Biology is the study of life and living organisms
behaviour
an observable action done by a human or animal
mental process
is the feeling thoughts inside of an individual
psychologist
6 years uni, focuses on therapy treatment,
psychiatry
11 years uni. trained as medical doctors. can diagnose and provide medical treatment as well as admit people to hospital
areas of psycholgy
Health Education Organisational Sports Clinical neuropsychology Clinical Community Counselling Forensic
CNS
Brain is the control centre of the body and the spinal cord carries messages to and from the brain and the body
PNS
Any nerve outside of the CNS, and carries messages to and from the brain and the body’s glands, muscles and organs
somatatic
Carries messages from the senses to the brain and from the brain to the muscles. like aches and pains and smells
Autosomatic
Includes the body’s non-skeletal muscles such as the heart and performs basic bodily functions such as digestion.
Parasympathetic
calms the body down and return to base line
Sympathetic
prepare for fight or flight response
BRAIN
Central Hub for body
SPINAL CORD
connects the brain to the PNS
structures that protect the brain
meninges, skull, cerebral fluid
occipital lobe
Vision contains the primary visual cortex
frontal lobe
Decision making, expression of emotion, personality - primary motor cortex
temporal lobe
Hearing and language comprehension - primary auditory cortex
parietal lobe
Receives and interprets information about touch, temperature and the position of muscles. Contains the somatosensory cortex
left hemisphere
maths and science, language, analytical thinking
right hemisphere
creativity, art and music, holistic thinking
brocas location
left frontal lobe
brocas function
speech production
brocas aphasia
ruins the production of speech, speaking slowly and only key words
wernickes location
left temporal lobe
wernickes function
speech comprehension
wernickes aphasia
affects the comprehension of speech. may speak regularly but add in unnecessary words
what is a neuron
A nerve cell which forms complex chains and networks which form neural pathways through information continuously travels
Dendrite
Receives information from other neurons and transmits it to the soma
Soma
AKA the cell body, contains the nucleus, maintains the cell and ensures that is keeps functioning
Axon
Carries message from the soma to the axon terminal
Myelin Sheath
White, fatty substance which coats and insulate the axon, helping to speed up the message
Axon Terminal
Stores and secretes neurotransmitters
Neurotransmitter
Chemical — which are used by the neurons to carry the message through the synaptic gap
exisitory and inhibitory neurontransmitters
the likely and unlikelyhood for the neuron to fire an action potential
ways brain damage can occur
Stroke Car crash Disease such as Alzheimer’s Alcohol Bain surgery Knock to the head
brain plasticity / have the ability to adapt and change
The brain has plasticity which means it is able to change in response to change. If a neuron is damaged then the surrounding neurons are able to make new connections with other undamaged neurons forming new neural pathways.
types of plasticity
Developmental
Adaptive
plactisity process
Synaptogenesis, reroouting, sprouting
Synaptogenesis
the formation of new connections between neurons
rerouting
When a neuron that is undamaged that has lost connection seeks a connection with another neuron
sprouting
growth of axon and dendrite branches to enable the neuron to make new connections.
cerebrum
area of the brain responsible for all voluntary activities of the body. located above the cerebellum
cerebellum
balance and coordination. located at the base of the brain
sensory neurons
neurons that carry incoming information from the sensory receptors to the brain and spinal cord
motor neurons
neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
interneurons
neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs
development plasticity
the natural changes that take place in all people’s brain as well grow older
adaptive plasticity
the ability of the brain to compensate for lost function in the event of brain injury
