Flashcards in The Brain Deck (21):
The Nervous system is divided into 3 main parts. Name them.
CNS- Central Nervous System
PNS - Peripheral Nervous System
ANS - Autonomic Nervous System
The 2 Brain hemispheres are connected by...
The corpus Calossum and other similar structures.
How is the brain connected to the tissues in the head?
How is the brain connected to the body?
The Spinal Cord.
Describe Neurons and their communications.
Functional units of the nervous system, communicate via Synapses and Neurotransmitters.
The spinal cord is split into sections according to Nerves. C1-8 T1-12 L1-5 S1-5 C0. Name the nerve types.
Name the 3 structures that make up the Brainstem.
The Reticular Formation is part of the Brainstem, what is its function?
Nuclei for sleep-wake cycles and arousal/consciousness.
The medulla oblongata (myencephalon) is part of the Brainstem. What is its function?
Centres for the control of vital processes such as:
The Pons (Metencephalon) is part of the Brainstem. What is its function?
Centres for the control of vital processes such as : Respiration and CV function.
Involved in coordination of eye movements and balance.
The Cerebellum (little Brain) is connected to the top of the Brainstem - What is its function?
Receives sensory inputs and sends motor outputs to coordinate balance, posture, walking and other movements.
Name the 4 main lobes of the Brain.
Describe the overall function of the Frontal Lobe.
Helps control skilled muscle movements.
Planning for the future, setting goals.
What are the sub-regions of the Frontal lobe?
Primary motor Areas
Ventromedial Prefrontal Cortex
Posterior and anterior Cingulate.
What are the 2 main areas of the Parietal Lobe?
Primary Somatosensory Cortex
Superior and Inferior Parietal Parts.
What is the Function of the Primary Somatosensory Cortex Found in the Parietal Lobe?
Recieves and processes information about touch, temperature, taste, pain and movement form the body.
Damage to this area effects contralateral skin sensitivity.
What is the function of the Superior and Inferior Parts of the Parietal Lobe?
Spacial Visualisation and analysis (right parietal lobe)
Interpretive centre for language, reading and mathematical calculations (left parietal lobe).
What is the overall function of the Occipital Lobe?
To process visual information from the optic nerve and lateral geniculate nucleus (part of the thalamus)
Conscious perception of visual stimuli.
Visual Processing is contralateral.
Damage causes blindness.
What are the sub regions of the Occipital Lobe of the Brain?
Primary Visual Cortex- V1, striate cortex, Brodman area 17.
Other visual areas - V2, V3, V3A, V4, V5.
What're the overall functions of the Temporal Lobe?
Hearing and Olfaction
Memory and Recognition.
