What are 3 major brain regions?
Forebrain
Brainstem
Cerebellum
What does cortex consist of?
Occipital lobe
Parietal lobe
Frontal lobe
Temporal lobe
What does cerebrum consist of?
Corpus callosum
Hippocampus
Basal ganglia
What does diencephalon consist of?
Thalamus
Hypothalamus
What does brainstem consist of?
Midbrain
Pons
Medulla
What are 2 divisions of cerebrum?
Cortex
Corpus callosum, hippocampus, basal ganglia
What does forebrain consist of?
Cerebrum
Diencenphalon
What is function of occipital lobe?
Visual processing E.g. colour, orientation , motion
What is function of parietal lobe?
Sensory processing
Proprioception
What is function of frontal lobe?
Decision making attention Consciousness Emotions Deliberate movement
What is function of temporal lobe?
Auditory processing
Language
Speech
Describe the structure of corpus callosum?
White structure which is made up of neurones/fibres which send communication to each other
What is function of corpus callosum?
Connects left + right hemispheres
What is function of hippocampus?
Memory formation
Memory retrieval
What is function of basal ganglia?
Movement
Balance
Posture
What is thalamus?
Where all info is sent to + is processed slightly by thalamus which then sends the info to appropriate brain region
What is hypothalamus + what is its function?
Collection of small nuclei Temperature Hunger/thirst Neuroendocrine control Key role in body’s response to stress Important in regulating our functions Is homestatic control
What is function of brainstem?
Important in maintaining homeostatic control + motor movement
Homeostasis=> breathing, heart rate + blood pressure
Motor movements=> reflexes, fine motor movements of limbs + face in conjunction with cortex
What is function of cerebellum?
Important in coordinating movement precision
What is function of spinal cord?
Transmits signals from/to the brain/body
What are 2 divisions of PNS?
Autonomic nervous system
Somatic nervous system
What is ANS involved in?
Unconscious control e.g. Heart rate, blood pressure, breathing + digestion
