Biopsychology Flashcards
What are the two main sections of the nervous system ?
Central Nervous System
Peripheral Nervous System
What are the two components of the Central Nervous System ?
The Brain
The Spinal Chord
What are the two components of the Peripheral Nervous System ?
Somatic Nervous System
Autonomic Nervous System
What are the two components of the Autonomic Nervous System ?
Sympathetic Nervous System
Parasympathetic Nervous System
What is the structure and function of the somatic nervous system ?
It is made up of sensory and motor neurons, it is conscious and in charge of voluntary movements
What is the structure and function of the autonomic nervous system ?
It consists of the sympathetic and the parasympathetic nervous systems, it is in charge involuntary actions such as internal organs and glands
What is the function of the CNS ?
It is in control of processing data received and transmitting signals to the rest of the body
What is a reflex arc ?
Where the body generates a response from a sensory input with the data being responded to by the spinal chord and not being processed by the brain, it is often to protect the body
What is the function of the frontal lobes ?
It is in charge of movement, decision making, logic and problem solving
What is the function of the Parietal lobes ?
It is in charge of the senses, temperature regulation and spacial awareness
What is the function of the occipital lobes ?
It is in charge of visual information and sight
What is the function of the temporal lobes ?
It is in charge of sound, memory and language
What is the function of the cerebellum ?
It is in charge of movement, co-ordination and balance
What is the function of the brain stem ?
It is in charge of unconscious functions of the body such as breathing and heart-rate
What is the function of the sensory neuron ?
It transmits sensory information to the CNS from the sensory receptors
Where are sensory neurons found in the body ?
In the PNS
What is the function of the relay neuron ?
It allows for the sensory and motor neurons to communicate, it passes information from
Where are relay neurons found in the body ?
In the CNS
What is the function of motor neurons ?
They take information from the CNS to the effectors (muscles and glands)
Where are the motor neurons found in the body ?
In the PNS
What common structures are found in all neurons ?
-Dendrites
-Cell body/Soma
-Axon
What is the function of dendrites ?
They receive information from other neurons
What is the function of the axon ?
It carries electrical impulses through the neuron
What is the function of the cell body/soma
It stores the organelles which maintain normal cell function, such as protein and lipid synthesis
