Q

Detail the charecteristics of the cerebrum 6

A
  • Consists of two Cerebral Hemispheres Left and Right
  • Refered to as the fore brain
  • Has a Cortex (surface) 2-4mm thick made up of Grey Matter
  • Middle of the Cerebrum (Medulla) consists of white matter connecting parts of the brain to the cortex
  • Cortex Highly folded convolutions (increases surface area)
  • Contains a sensory Cortex process sensory information detected by sensors in the skin and sensory organs touch, pressure etc

Q

Detail the charecteristics of Broca’s area 4

A

Also known as the Motor Speech

Located near the motor cortex

It regulates vocalizations required for normal speech.
Words are formulated for repetition here

17
Q

What are the different types of Memory

A

Sensory
Short Term
Long Term

18
Q

Detail Sensory Memory

A

Very short term (less than 1 sec)

Retention of sensory input during which
time it is scanned, evaluated and acted upon

e.g. touch an object - a short term memory is created - you will decide if you continue touching or remove hand because its unpleasant

19
Q

Detail Short Term Memory

A

Limited to 7 bits of info

Stored within the Temporal Lobe

Formed due to temporary changes in the
membrane of the cells in that area

20
Q

Detail Long Term memory

A

Refered to as Declrative (Explicit Memory
Consists of the retention of Facts
Recall - located in the Hippocampus within Medial Temporal Lobe
Empotion Fear - located in the Amygdala

21
Q

What are the two forms of Long Term Memory

A

Procedural Memory - located in the Cerebellum and is the memory of learnt skill e.g. riding a bike

Rehersal Memory - Converts short term memory to long term memory and requires protein synthesis

22
Q

What is the function of the Basal Ganglia

A

Plays a major role in
⚫ voluntary motor functions,
⚫ procedural learning
⚫ Routines or habits
⚫ Eye movements
⚫ Also contributes to cognition and emotions

23
Q

Detail the Limbic System

A
  • Consists of the Cerebrum and the Diencephalon
  • This influences emotions, motivation,
    mood and sensations of pain and
    pleasure.
  • Associated with basic survival
    instincts and reproduction.
24
Q

Detail the Spinal Cord

A
  • 45cm Long extends from Medulla to the 2nd Lumbar Vertebrae
  • Protected by Miningies
  • Diveded into 31 segments
  • 8 Cervical C1 - C8
  • Thoracic T1 -T12
  • Lumbar L1 - L5 (PODIATRY RELATED)
  • Sacral 5
  • Coccygeal 1
25
Q

The auditory cortex is responsible for hearing and language. In which part of the cerebral cortex is it located?

A

The temporal lobe houses the auditory cortex, which processes the sounds we hear.

26
Q

The somatosensory cortex is an area just behind the motor cortex that receives information from the skin’s sensory receptors and movements from different body parts. In which part of the cerebral cortex is it located?

A

The parietal lobe houses the somatosensory cortex, which receives information sent from our senses

27
Q

Damage to (the) ________ disrupts one’s ability to comprehend language, but it leaves one’s ability to produce words intact.

A

Wernicke’s Area is responsible for the comprehension of language. As long as damage was isolated to this area, a person would still be able to produce words.

28
Q

The motor cortex sends messages to specific regions of the body to create movement. In which part of the cerebral cortex is it located?

A

The frontal lobe houses the primary motor cortex, which sends signals to move our muscles.

29
Q

Match the correct functions to the associated regions of the brain. 1.Frontal Lobe
2.Parietal Lobe
3.Temporal Lobe
4.Occipital Lobe

Visual info, processes what we see
Voluntary Movement, Emotion and higher brain function
Sensory, linked to sensory cortex touch, pain
Auditory processing

A

Frontal - Voluntary Movement, Emotion and higher brain function
Parietal - Sensory, linked to sensory cortex touch, pain
Temporal - Auditory processing
Occipital - Visual info, processes what we see
