Q

What is the make up of myosin

Proteins important in movement of muscles in the body

A
  1. Made up on many individual myosin protein molecules
  2. Myosin protein is NOT globular
  3. It has a head and a tail
  4. Each complete myosin molecule in muscle is composed of 2 or 3 head-and-tail molecules, twisted around each other
  5. Then, to make the myosin filament, you have to take these doublet myosin molecules and put them together into large bundles
  6. This big wad of myosin proteins, is then called the THICK FILAMENT
  7. A single thick filament has over 200 myosin molecules
  8. It is really thick!

Q

Evaluating the amount of Damage Done Due to Burns

A

1st Degree

  1. Involves only Epidermis
  2. Redness, Pain, Slight Swelling
  3. Can be caused by sunburn or exposure to hot or cold objects
  4. Heal in week or 2, with no scar

2nd Degree

  1. Damage Epidermis + Dermis
  2. Causes Redness, Pain, Swelling, Blisters
  3. Heal in approximately in 2 weeks
  4. No Scarring

3rd Degree

  1. Epidermis and Dermis are completely destroyed
  2. Often surrounded by 1st and 2nd degree burns (which are painful)
  3. the 3rd degree burns often painless because sensory receptors have been destroyed
  4. Appear white, tan, brown, black, or deep cherry red

Q

Stretching of Muscles

A
  1. Form of physical exercise in which a specific muscle or tendon is deliberately flexed or stretched in order to improve the muscles felt, elasticity + achieve comfortable muscle tone
    Result–Feel of increased muscle control, flexibility + range of motion
    Stretching helps alleviate cramps

17
Q

What is Gouty Arthritis

A

Attack that is extremely painful with joint inflammation due to deposits of uric acid crystals in the joint fluid + joint lining

18
Q

Survival Needs of the Body

A
  1. Proper Body Temperature
  2. Oxygen
  3. Water

19
Q

Where do Cranial Bones Originate From

A

Sutures

20
Q

Amino Acids + Peptides = __________

A

Proteins

21
Q

How does Ach work in Synaptic Clefts

A
  1. The normal stimulus for neurmtransmitter release is the depolarization of the synaptic cleft by the arrival of an action potential
  2. The entry of calcium ions into the synaptic cleft, triggering the exocytosis of Ach
  3. The depolarization of the synaptic cleft opens voltage-regulated calcium channels
    In the brief period during which these channels remain open–calcium ions rush into the synaptic cleft
  4. Their arrival triggers exocytosis and the release of Ach into the synaptic cleft
    The release of Ach stops very soon
  5. The Ach released through exocytosis diffuses across the synaptic cleft toward receptiors
  6. The more Ach released through the presynaptic membrane, the larger the depolarization
  7. The Ach molecules that succeed in binding to recpetor sites are broken down within 20 msec. of their arrival
  8. The enzyme AChE breaks down molecules of Ach into acetate and choline
  9. The choline is absorbed by the synaptic cleft and is used to synthesize more Ach
