Biopsychology Flashcards
What is the function of the genes?
They pass characteristics from generation to generation
How does a characteristic develop?
Through interaction with other genes and the environment
The extent to which a psychological characteristic is determined by genes or environment is called
The nature-nurture debate
Genotype
Genetic coding
Phenotype
Observable characteristics
What is the nervous system?
The primary internal communication system
The central nervous system consists of
The brain and spinal cord
The peripheral nervous system consists of
The ganglion and the nerve - the somatic and autonomic nervous systems
Somatic nervous system
Communicates with sense organs and voluntary muscles
Autonomic nervous system
Communicates with internal organs and glands
How does the nervous system carry messages?
Through neutrons in the form of electrical signals
Sympathetic division
Arousal
Parasympathetic
Calming
Sensory nervous system
Sensory output
Motor nervous system
Motor output
The autonomic nervous system is made up of
The sympathetic diction and the parasympathetic division
The somatic nervous system is made up of
The sensory nervous system and the motor nervous system
The largest part of the brain is the
Cerebellum
The outer surface of the cerebellum is called the
Cerebral cortex
The cerebellum is split into two halves called
Hemispheres
The hemispheres are divided into four different parts which are called the
Lobes
What is release when a nerve impulse reaches the end of one neuron
A neurotransmitter
What is the junction between two neurons called?
Synapse
Excitatory neurotransmitters
Trigger nerve impulses
Inhibitory neurotransmitters
Stop nerve impulses (to calm)
Dendrite
Receiving end of the neuron
Axon
Passes electrical impulses form the cell body to its end where neurotransmitters are secreted into the synapse
Communication between neurons is
Chemical
Communication within neurons is
Electrical
Charge of the inside of a cell
Negative
When a neuron is stimulate the inside becomes …… Charged for a split second.
Positively
Hormones are secreted into the bloodstream to find their
Target cells
