test for psych Flashcards
what is the hindbrain
an area of the brain located at the bottom and control basic functions. it holds the cerebellum, the medulla and the pons
what is the cerebellum
a ball like structure that regulated memory formation, balance and voluntary movement.
what is the medulla
a mass of neurons that control autonomic functions as well as connecting the brain and spine
what are pons
small structure that regulates sleep as well as relaying information to the brain
what are brain stems
extensions of the spinal cord
what is the midbrain
a part of the brain that separates the hindbrain and forebrain. it is apart of the brain stems and its main functions are processing sensory information and sleep regulation.
what is the reticular formation
a net like structure of neurons that connect parts of the brain. main functions are decrease and increase in alertness, sleep and adjusts muscle tension
what is the forebrain
the largest part of the brain which holds the thalamus, the hypothalamus and the cerebrum. Involved in complex functions and coordination
what is the thalamus
oval like structure that’s apart of motor control, attention and letting sensory information except smell pass through.
what is the hypothalamus
an almond shaped structure that’s apart of emotional nd motivated behaviour as well as sleep cycle and hunger.
what is the cerebrum
largest uppermost area of the brain that is connected by the corpus callosum. its functions include language perception and evaluation
what is the occipital lobe
a lobe for vision
what is the parietal lobe
spatial awareness and processing sensory information
what is the temporal lobe
memory, processing auditory information and visual perception.
what is the frontal lobe
personality, taste perception and voluntary movement.
what are motor neurons
neurons that communicate info on movement
what are sensory neurons
neurons that communicate info on body sensations
what are interneurons
neurons that relay information between the motor and sensory neurons.
what are glial cells
they are cells that support and protect neurons by holding them in place and supplying them with oxygen and nutrients.
what is the function of a dendrite
receive neurotransmitters
what is the function of an axon
messages are transmitted
what is the function of a myelin
speeds up transmission
what is the function of an axon terminal
release neurotransmitters to the synapse.
what is a neuron
a cell used to communicate with in the nervous system
left hemisphere of the brain functions
reading
writing
speaking
right hemisphere of the brain functions
spatial awareness and visual awareness.
what is localization of function
certain areas of the brain being more specialised in certain functions
