GENERAL Flashcards
WHAT DO APPENDIX’S DO?
-storage for lymphatic cells
-part of MALT
-plays a role in body immunity
M.A.L.T. FUNCTION
-“Mucosa-associated lymphoid tissue”
-lymphoid tissues that helps protect against pathogens.
-includes the tonsils, Peyer’s patches and appendix
WHAT DOES SALVIA DO?
- Moistens/cleans mouth
- Inhibits bacteria growth
- Dissolves material
- Digests starches/fats
- Binds/lubricates bolus
LAYERS OF DIGESTIVE TRACT
(from inside out)
1. Mucosa
2. Submucosa
3. Muscularis Externa
4. Serosa
WHAT DO BACTERIA DO IN THE L.I?
-provide nutrient from food that we cannot extract ourselves
-also synthesizes vitamin B and vitamin K
-also adds to amount of gas through digestive tract
WHAT DOES LEPTIN DO?
-long-term gut-brain regulator
-level is in proportion to amount of adipose one has
-brain’s primary way of knowing how much adipose we have
-primary function to increase appetite and food intake
WHAT IS METABOLISM?
-the sum of all biochemical reactions in the body
-anabolic (dehydration synthesis) and catabolic (hydrolysis)
WHAT PROCESS PRODUCES MOST ATP
oxidative phosphorlation: glucose metabolism
PRODUCTS OF ANAEROBIC RESPIRATION
-2 ATP PER GLUCOSE
-LACTIC ACID
PRODUCTS OF AEROBIC RESPIRTATION
-32 ATP
ISOTONIC CONTRACTION
-tension in muscle remains constant while muscle changes length.
CONCENTRIC CONTRACTION: tension great enough to overcome load, muscle shortens (picking up a book)
ECCENTRIC CONTRACTION: tension resists movement of load and slows lengthening process (slowly lowering a book)
ISOMETERIC CONTRACTION
-tension in muscle is not great enough to overcome load on muscle and there is no change in length
WHAT DOES A MOTOR UNIT CONSIST OF?
-MOTOR NEURON
-SKELETAL MUSCLE FIBRE
TWITCH CONTRACTION
-brief contraction of a muscle fibers in a motor unit - response of single stimulation
WHAT IS A CONTRACTION MEASURED ON IN LAB?
MYOGRAM
