Psychobiology Flashcards
CNS
Brain and Spinal cord
Somatic PNS
Sensory and motor processes
eg. Touch
Autonomic PNS
Monitors automatic processes
eg. Heart rate
Nerves
Are collections of individual nerve processes
Neurons
A specialised type of cell
Transmits info to, from and within the CNS
Neuraxis
An imaginary line drawn through the spinal cord and then up to the front of the brain
Distal
Away
Proximal
Near the head
Ventral
Front
Dorsal
Back
Lateral
Outwards
Medial
Inwards
Sliced brain across
Frontal and cornal
Slice brain lengthways
Sagittal
Slice brain lengthways in the middle
Midsagittal
Parallel to the ground
Horizontal
Frontal lobe
Reasoning, planning and speech
Temporal lobe
Perception and memory
Parietal
Orientation and recognition
Occipital
Visual processing
Limbic
Emotion and memory
Prefrontal cortex
Region of the frontal lobe
Motor cortex
Rear of the frontal lobe
Primary somatosensory cortex
Along the central sulcus
Visual cortex
Inner surfaces of occipital lobes
Cerebellum
At the back.
Associated with h coordination of movement, posture and balance
Phenotype
Observed traits
Genotype
Transmitted genetically
Alleles
Two genes controlling the same trait
Genes are located on…
Chromosomes
Meiosis
Pairs of chromosomes are divided between gametes
Mitosis
Cellular division
Meninges
Protective membranes under the skull
Soma
In a cell.
Contains the nucleus and mitochondria
Axon
Like a wire that carries electricity
Dendrites
The main recipients of information from other neurons
