Reflex and reaction Time lab...
***You MUST ALWAYS prepare with PRE-LAB...being familiar with directions and expectations posted on this page...SAFETY FIRST! Unprepared is NOT safe!
 1. Patellar Knee Reflex
2. Babinski Reflex
3. Reaction Time Test-using calculated times WS...
Groups of 3 already chosen...
Completed WS must be turned in(1 per group) for Lab credit!
Labs may NOT be made up unless discussed with teacher prior.
HW: Always review previous lesson and web page...

Cranial Nerves-12 pairs...
Roman numerals review: I = 1, V = 5, X = 10,L = 50, C = 100, D = 500, M = 1000
***An I before a V or X = 1 less than the V or X, ex. IV = 4, IX = 9
***An I after a V or X = 1 more than the V or X, ex, VI = 6, XII = 12
XL = 40, LX = 60, MCMLXXIV = ????

**Meninges video from today: https://youtu.be/8-XVv5pv7Ss

***Meninges are 3 membranes that cover and surround the brain and spinal cord. mnemonic D-A-P
Meninges...
the three membranes (the dura mater, arachnoid, and pia mater) that line the skull and vertebral canal and enclose the brain and spinal cord.
FOR QUIZ:
Dura Mater-outermost
Arachnoid Mater-middle
Pia Mater-innermost
Subarachnoid space...this is where CSF: Cerebrospinal fluid which is a 'shock absorber' of the brain
***Epidural-for pregnancy injected anesthesia into Dura Mater of Lumbar vertebrae...


***Reflex hammers-Taylor-most common-QUIZ

HWWatch the Babinski reflex for tomorrow's lab...

***Watch the reaction time video for tomorrow...we will use a conversion sheet ...
https://youtu.be/81lPJtAp5Sc
***Reaction time involves a very complicated physics formula...I included a conversion table that computed the math to save time on Wednesday...
***Each lab group of 3 works professionally and turns in 1 completed ws completely filled out for grade...
Labs may not be made up for absentees unless with teacher permission at appointed time...
Wednesday for students who wish to be 1 step ahead-shorter periods on Wed.

MEMORIZE

***Broca's area is the motor speech area and it helps in movements required to produce speech. ... This is called Broca's aphasia. Wernicke's area, which is located in the parietal and temporal lobe, is the sensory area. It helps in understanding speech and using the correct words to express our thoughts.
Aphasialoss of ability to understand or express speech, caused by brain damage.
