Neuroanatomy Flashcards
1
Q
Neuroanatomy is …
A
- refers to the structure of there brain and nervous system
2
Q
What is the structure of the brain?
A
- divided into two hemispheres (left & right)
- brain has localised brain function
- means that different brain areas perform certain specific functions
3
Q
Motor cortex is …
A
- frontal lobe area
- each hemisphere has a motor area which controls voluntary movements of opposite sides of the body
4
Q
What is an example of the motor cortex controls?
A
- facial/ arm/ tongue movement
5
Q
Somatosensory area is …
A
- patiental lobe area
- in both hemispheres
- sensory information from skin is represented here in proportion to sensitivity of body parts
6
Q
What is the example of somatosensory area control?
A
- heat
- pain
- touch
- proprioception
7
Q
Visual cortex is …
A
- occipital lobe area
- back of both hemispheres
- processes visual information
- each eye sends information to opposite hemisphere
- damage to one visual area can cause partial blindness in both eyes
8
Q
Thalamus is …
A
- passes sensory impulses from receptors in body to cerebral cortex
- sensory impulses travel from body surface towards thalami receives it as a sensation
- sensation passed to cerebral cortex for interpretation as touch, pain or temperature
9
Q
Amygdala is …
A
- temporal lobe area
- responsible for the perception of emotions such as anger, fear and sadness & controlling aggression
- helps store memories or events and emotions so individuals can recognise in the future future
– Example dog bite remembered, processed and increases fear or alertness around dogs
10
Q
Orbital frontal cortex is …
A
- pre frontal cortex area
- responsible for decision-making, impulse control and rational thinking
– Reduce activity of OFC which inhibits ability to regulate impulses such as aggression
– Argument used for those with aggressive behaviours
11
Q
What area of the brain was affected by the Phineas Gage study?
A
- pole through frontal lobe
12
Q
Localisation of function is …
A
- different brain areas perform certain specific functions
– Outer layer cortex is thin highly folded with covers - structures of the brain are highly developed
13
Q
What are the sex differences in brain structure?
A
– Males have greater brain volume
– Males have a larger thalamus stronger nerve connections between hemispheres of the brain and their cortex is thicker
14
Q
what is a strength evaluation for neuro anatomy?
A
- support for sex differences
- Ingalhaliker 2014
- men have stronger connections within hemispheres than women
– Found an MRNI scans
Differences between female and male brain function
15
Q
what is a weakness evaluation of neuro anatomy?
A
– Structure not function
– Little research with few conclusions
– Differences in structure not function
