1

3 levels of neural control

1. Cortex
2. Subcortical structures ( brainstem, cerebellum)
3. Neuromuscular system/ sensory system

2

3 phases of tissue healing

1. Inflammatory phase (2-4 days)- swelling, edema, redness, pain

2. Proliferation/fibroblastic repair (4-6w)- damaged tissue is replaced w new scar collagen tissue

3. Maturation phase- reestablishing tensile strength of scar tissue + collegen refining

3

5 factors that effect healing/ performance

1. physical- serverity, poor blood supply, infection, age
2. autonomic influence- sympathetic drive may result in referal pain to other regions
3. Emotional/psychosocial influence- increase stress/ anxiety/depression
4. Preexisting conditions- orthopedic, neurological +/or sensorimotor conditions may prolong recovery
5. Motivation/adherence- requires the motivation to adhere to a rehab program

4

How can HCP improve rehab outcomes

-holistic view
-provide positive reinforcment
-active listening/support
-patient/athlete advocacy

5

how many hemishepes in each lobe

5

6

%s of brain regions

cerebral cortex- 82%
cerebrellum- 10%
basal ganglia- 8%

7

Frontal lobe seperated by which sulcus

seperated from temportal lobe by lateral sulcus

8

two functions/ areas of frontal lobe

1. prefrontal cortex- cognition ( executive function, judgement, memory)
2. Motor areas (broadmanns area 4 + 6)

9

function of brodmann area 4, what does it contain and where does it project to

-mediates voluntary movement of limbs in trunk
-contains bertz cells- projects to corticospinal tract

10

Structures of brodmann area 6, projects to, function

-premotor cortex- integrates sensory info for movement planing

-supplementary motor area- part of motor loop w basal ganglia

projects to M1, brainstem, spinal cord
-planning, prep for movmt

11

cingulate motor area

lmbic system connections (motivation, internal state of indv.)

12

3 areas of parietal lobe

-somatosensory area- proprioception, touch, sensory localization

-superior somatosensory cortex

- Posterior perietal cortex- attn, planning movement, integration of visual info

13

2 areas of visual system

Primary visual cortex (V1)
Visual association cortex (V2-6)

14

2 streams of visual system

Dorsal (magnocellular)- motion, depth, temporal resolution
Ventral (parvocellular) - V3-6 - fine details, colour, spacial resolution

15

where does the optic nerve decussates

@ the optic chiasm

16

where does the optic nerve project to

to lateral geniculate nucleus in the brainstem to v1-6 --> dorsal + ventral streams of perception

17

What is located in the temporal lobe?

-Primary auditory cortex superior
- Wernicke's area (comprehension of language)
- inferior surface- associated w high order visual processing

18

What are the structures in the limbic lobe and what is the function

-cingulate + parahippocampal gyri
- cingulate gyrus immediately superior to corpus callosum

-emotions, driven behaviours, memory

19

Dienchephalon 4 divisions

1. thalmus
2. hypothalmus
3. epithalmus
4. subthalmus

20

Thalmus location

protrues over the superior portion of the brainstem, borders the 3rd ventricle

21

two motor loops of thamus

motor cortex cerebellum
motor cortex basal ganglia

22

Hypothamus function

-controls ans
- maintains homeostasis, regulates body temp, visceral responses, some limbic function

23

Conduit (relay nuclei)- functions and tracts

ascending- cerebelum, thalmus- crude touch and pressure, light touch and proprioception

decending-> spinal cord, trunk and limbs

24

Cranial nerves: motor and sensory functin

sensory- olfaction, vision, hearing, taste
motor- facial ex, tounge movement, swallowing
