Biological PSY wk 3 Flashcards
What do the Sensory Neurones do?
and where is it located?
Send a message from the brain to the body, (Eg. Temp, pressure, pain)
Location : dorsal spine
What do the Motor Neurones do?
and where is it located?
Send messages from the brain to the body, (Eg. Actions, changes in organ function)
Location: Ventral Spine
What do Interneurons do?
Connect sensory and motor Neurones at the spinal level, allowing reflexive movement
What does the Brain stem comprised of?
mid-brain, pons, medulla and RAS
what is the cerebellum also known as?
The little brain
What does the cerebellum do?
gives people; balance, motor coordination, learning and motor skills
what are cerebral Ventricles?
cavities within the brain that contain cerebrospinal fluid,
What does cerebrospinal fluid do?
Nourishes and protects the central nervous system
What are the 2 main purposes of the Brain stem?
1- Connects the brain and spinal cord 2- Regulates bodily functions
what are the 4 key functions in the brain stem?
1- pons
2-Medulla
3-Mid- brain
4-Reticular activating system (RAS)
What does the pons do?
connects cortext to cerebellum
what does the medulla control?
Respiration, heart rate and sleep/wake patterns
what does the mid-brain control?
Movement control, orienting to sensory stimuli
what does the RAS control?
continuousness an arousal
if an individual was classified as brain dead, which of the four key functions would not be working?
All.
What is the largest most complex region of the brain?
Forebrain
What is the two main things the Forebrain is comprised of
1 - cerebral cortext
2- subcortical structures
What is the left and right cerebral hemispheres connected by, that allows the two hemispheres to share information
corpus callosum
what is the lymbic system?
interconnects brain regions, involved in emotional processing, basic drives, control of the autonomic nervous system, learning & memory and smell.
(ALSO 1 OUT 2 KEY SUBCORTICAL STRUCTURES)
what are the 4 key things that the lymbic system is made up of?
Thalamus, hypothalamus, Amygdala, Hippocampus
