Biopsychology(nervous system - central nervous system) Flashcards
The nervous system -
The human nervous system is a complex network of nerve cells that carry nerve cells to and from the brain and spinal cord.
Spinal cord -
A large bunch of axons, that travels all the way down to the back from the brain. Due to the axons it allows to control and feel the body and regulate internal bodily functions, (coordinate voluntary functions) its connected with nearly all parts of the body and is protected by the spinal column.
Brain -
The brain receive information from the sensory receptors and send messages down to muscles and glands and this involves the spinal cord where the spinal cord relay information between the brain and the rest of the body.
4 parts of the brain -
- Cerebellum
- Cerebrum
- Diencephalon
- Brain stem
Brain stem -
Responsible for regulating automatic functions essential for life, the brain stem allows impulses to run from the brain to the spinal cord.
Cerebellum -
Sits beneath the back of the cerebrum, involved in controlling motor skills, balance and coordinating muscles.
Cerebrum -
- Divided into 4 lobes, and each lobe has a different primary function.
Parietal lobe (cerebrum) -
Processes sensory information. For example, touch, pain
Frontal lobe (cerebrum) -
Involved in speech production, thought, impulse memory and working memory
Occipital lobe (cerebrum) -
Visual information
Temporal lobe (cerebrum) -
Involved in hearing, language and comprehension.
Diencephalon -
Situated on top of the brain stem and contains two important structures the thalamus and hypothalamus.
Thalamus (diencephalon)
Acts as a relay station for nerve impulses from the coming from the senses including in functions of sleeping
Hypothalamus (diencephalon)
Regulation of body temperature, hunger and thirst, acts as a link between endocrine system and nervous system.
