What is the brain surrounded by?
3 membranes - meninges
1 of 40
How much does the brain weigh?
2 of 40
Function of meninges
Protection of brain and spinal cord
3 of 40
What fills the 4 ventricles in the brain?
Cerebro-spinal fluid
4 of 40
Main functions of cerebro-spinal fluid
Supplies neurons with Oxygen and glucose. Protects against shocks and mechanical injuries. Maintains a constant pressure in and around brain
5 of 40
3 main regions of brain
Hindbrain, midbrain, forebrain
6 of 40
What components of brain in hindbrain?
Medulla oblongata and cerebellum
7 of 40
What components of brain in midbrain?
Nerve fibres, links forebrain to hindbrain
8 of 40
What components of brain in forebrain?
Hypothalamus,thalamus and cerebrum
9 of 40
Medulla oblongata function?
Control of breathing,heart rate and blood pressure. Also contains many important centres of ANS
10 of 40
Hypothalamus function?
Co-ordinating centre between nervious system and endocrine system. Homeostatic functions, body temp, blood solute conc and thirst, hunger and sleep
11 of 40
Thalamus function?
Relay centre, sends and recieves info to and from cerebral cortex,has a role with sleep and sensory interpretation
12 of 40
Hippocampus function?
Learning, reasoning and personality, limbic system structure important in forming new memories
13 of 40
Cerebellum function?
Maintenance of posture and co-ordination of voluntary muscles e.g. writing,requires carefully co-ordinatedmovements
14 of 40
Cerebrum function?
Controls all higher mental activities, largest division of brain, two hemispheres
15 of 40
Main two components of nervous system?
Central nervous sytem and peripheral nervous system
16 of 40
Brain and spinalcord
17 of 40
Motor neurons and sensory neurons
18 of 40
Divisions of autonomic nervous system?
Sympathetic nervous system and parasympathetic nervous system
19 of 40
Motor neurons division
Somatic nervous system and autonomic nervous system
20 of 40
What does the SNS do?
Controls voluntary movement
21 of 40
What does sympathetic division do?
Fight or flight
22 of 40
What does parasympathetic division do?
Rest and digest
23 of 40
What does ANS control?
Involuntary responses
24 of 40
Frontal lobe
Speech +movement - motocortex, emotions, personality, problem solving, reasoning and planning
25 of 40
Temporal lobe
Language organisation and comprehension, learning and memory, hearing
26 of 40
Occipital lobe
Vision processing,integrating and interpreting
27 of 40
Parietal lobe
Sense integration, spatial awareness and perception - proprioception
28 of 40
Balance/posture and coordination of muscles
29 of 40
Brain stem
Blood pressure, heart rate, ventilation rate, swallowing, consciousness
30 of 40
Is SNS involved in heart rate control?
31 of 40
Is ANS involved in heart rate control?
32 of 40
Does SNS has conscious or sub-conscious control?
33 of 40
Does ANS have conscious or sub-conscious control?
34 of 40
Rest and digest
Inhibitory effect, increases peristalsis, decreases heart rate and ventilation - acetylcholine
35 of 40
Fight or flight
Excitatory effect on most parts, peristalsis reduced, heart rate increased - noradrenaline, sweating stimulated, blood to muscles
36 of 40
How do sympathetic and parasympathetic divisions work together?
Antagnastically, mammals rarely fully relaxed or active. Opposing signals from 2 types of neurons adjust an organs action to an appropriate level e.g.heart rate
37 of 40
Sensory areas
Receive nerveimpulses from receptorsin body, hemispheres recieve info from other sides of body.
38 of 40
Parts of cerebral cortex that first recieve impulses
Primary sensory areas - e.g. thalamus
39 of 40
Association areas
Process and interpret information, make up most of cerebral cortex. Use previously stored info to interpret info from primary sensory areas to give meaning
