Week 3+4 biological Bases Of Behaviour And Mental Processes Flashcards
What is the peripheral nervous system?
Carries messages to and from the central nervous system
What is the graded potential?
Are the spreading voltage changes along the cell membrane that occur as the neuron is the firing of the neuron or a nerve impulse
What transmits information from one neuron to another as they are released into the synapse, what is it called?
Neurotransmitters
Motor neurons
Transmits commands from the brain to the glands and muscles of the body
What connects neurons with one another?
What is it called?
Interneurons
What is a neuron?
Generally have a cell body, dendrites and an axon that carries information to other neurons
What are the two subdivisions of peripheral nervous system?
Somatic and autonomic nervous system
Somatic nervous system?
Carries sensory information to the brain and motor neurons that direct the action of skeleton muscles
What nervous system controls the basic life processes such as heart beat and breathing?
Autonomic nervous system
The autonomic nervous system consists of two parts what are they called and what do they do?
The sympathetic nervous system activated in response to threats and the parasympathetic nervous system involved in routine activities
Endocrine system?
Is a collection of glands that control various bodily functions through the secretion of hormones, sends global messages through the bloodstream
Carries out reflexes, transmits sensory information to the brain and transmits messages from the brain to the muscles and organs
What is it?
The spinal cord?
What is the medulla oblongata?
What part of the body does it belong to?
Extension of spinal cord that regulates heartbeat, circulation and respiration
Hindbrain
What parts are involved in the hindbrain?
Medulla oblongata
Cerebellum
Reticular formation
Pons
What is the cerebellum?
Where does it belong?
Involved in movement, learning and sensory discrimination
Hindbrain
What is sensory neurons?
Carry sensory information from sensory receptors to the central nervous system
A network of neurons involved in consciousness and arousal what is it called?
Where is this is the brain?
Reticular formation
Hindbrain
What are pons?
Where do they belong?
Links medulla oblongata and cerebellum with upper part of brainstem
Hindbrain
What is part of the midbrain?
Tectum
Tegmentum
Plays an important role in learning to produce behaviours that minimize unpleasant consequences and maximize pleasant consequences
What is a tectum?
Where is it located?
Involved in orienting to visual and auditory stimuli
Midbrain
What is the tegmentum?
Where is it located?
Is involved in movement and arousal
Midbrain
What is part of the forebrain?
Hypothalamus
Thalamus
Basal ganglia
Helps to regulate eating, sleeping, sexual activity and emotional experiences?
Where is it located?
Hypothalamus
Forebrain
What is a thalamus?
Where is it located?
Processes incoming sensory information and transmits it to higher brains areas
Forebrain
What is a basal ganglia?
Where is it located?
Involved in the control of movement and also plays in ‘automatic’ responses and judgements
Forebrain
What system is the septal area, amygdala, hippocampus in?
Limbic system
Septal area?
Involved in pleasure relief from pain, emotionally significant learning
Limbic system
Amygdala what is it?
Where is it located?
Involved in learning and remembering emotionally significant events and recognition of fear
Limbic system
What is the hippocampus?
Where is it located?
Involved in the storage of new memories
Limbic system
What is the heritability?
Refers to the proportion of variability amoung individuals on an observed characteristic that can be accounted for by genetic variability
What are the functions of cerebral cortex?
Provides for flexible control of patterns of movement
Permits subtle discrimination amoung complex sensory patterns
Makes possible symbolic thinking
What are the four sets of lobes in the cerebral cortex?
Occipital lobes
Pariental lobes
Frontal lobes
Temporial lobes
The primary and association areas of the cortex are involved in…
The complex mental processes such as perception and thinking
