Q

What are the different cotrical areas of the brain?

A
  • The motor areas - primary motor cortex
  • Sensory areas - primary somatosensory cortex

Q

What is the function of the prefrontal association areas/

A
  • ## Idea and plan for voluntary movement, thoughts and personality
16
Q

What is the function of Broca’s area? Location?

A
  • Speech formation
  • Located in inferior forntal gyrus of the dominant hemisphere
  • Lesion leads to Broca’s aphasia
  • Difficulty generating written or spoken language
  • No/ little difficulty with language comprehension
17
Q

What is the function of the olfactory cortex?

A

Smell

18
Q

What is the function of the limbic association cortex?

A
  • emotions, learning, and memory
19
Q

What is the role of the primary auditory cortex?

A
  • Hearing
19
Q

What is the role of the primary somatosensory cortex?

A

-Somaesthetic sensations and proprioception

20
Q

What is the role of the sensory association areas?

A
  • Integration of sensory information
21
Q

What is the function of the visual association areas?

A
  • Higher visual processing
22
Q

Wilkommen

What is the function of Wernicke’s area ? Location?

A
  • Language comprehension
  • Lesion leads to difficulty understanding written/spoken language
  • Person can generate speech but language = meaningless/ unconnected
  • located in the superior temporal gyrus of fominant hemisphere
23
Q

ACP

What are the different fibres of the cerebral white matter tracts?

A
  1. Association : connect cortical areas within hemisphere (short/long association fibres)
    - Named longitudinal bands ( superior longitudinal fasciculus)
    2.** Commissural fibres: connect cortical areas of the two hemispheres
    - corpus callosum/anterior commisure (allows coordination e.g walking)
    3.     Projection fibres** : connections between cortex and subcortical structures (thalamus, basal ganglia)
    - internal capsule (thalamacortical fibres)
24
Q

Describe the spinal cord

A
  • 31 pairs of spinal nerves:
  • **Cervical (C1-C8)
  • Thoracic (T1-T12)
  • Lumbar (L1-L5)
  • Sacral (S1-S5)
  • Coccygeal (Co1)**
  • Each spinal cord segment gives rise to one pair of segmental spinal nerves
  • SC continous cranially with the medulla oblongata and terminates caudally as the conus medulllaris around L1/L2 vertebral level
25
Q

Look like strings

What is the function of ventral rootets?

A
  • Carry axons of the somatic morot neurons, sympathetic neurons (T1-L1/2) spinal nerves only and parasympahetic neurons (S2-S4 spinal nerves only)
26
Q

What is the function of the dorsal (posterior) rootlets and dorsal root?

A
  • They contain the central processeses of pseudo-unipolar somatic sensory neurons and visceral afferent (sensory) neurons
  • Join with ventral roots to form a spinal nerve
