1. The myosin head attaches to an ATP molecule > The myosin head hydrolyzes the ATP molecule to ADP and phosphorus and the energy that is released is used to energize the myosin head and pigeon it forward > The myosin head latches on to the actin microfilament to form a cross-bridge > The inorganic phosphorus is released causing the myosin head to pull the actin microfilaments toward the m line, and then release the ADP molecule > the cross-bridge is broken and the myosin returns to its none energized state.

2. Echondrial ossification is the process in fetal development where cartilage hardens into bone tissue. On the other hand, intramembranous ossification is the formation of bone tissue from scratch.

3. Anagen is the growth phase. Catagen is the transitional phase. Telogen is the resting phase

1. Where is the calcaneus located and what type of bone is it?

2. What are the three hamstring muscles?

3. What are types of skin glands
1. It's located in the foot (heel) and it's a short bone
2. Biceps femoris, semitendinosus, semimembranosus
3. Sudoriferous (sweat) glands and sebaceous (oil) glands

1. Correct
2. Close, Biceps femoris, semitendinosus, Semimebranosus
3. Close, You are just missing ceruminous glands. They produce ear wax.

3. What is scoliosis? Discuss possible causes, diagnosis methods, symptoms, and treatment for this condition.
1. A?
2. stratum basale, spinosum, granulosum, lucidum, and corneum
3. Scoliosis is an abnormal curvature in the spine.
-Causes are difficult to pin down, however, it can be caused by birth defects or infection/injury to the spine.
-Some diagnosis methods include examing the "bumps" from spinous processes on a patient's back for curvature in the frontal plane, x-rays, CT scans, and performing an MRI. The degree of curvature is also diagnosed to asses the severity of curvature.
-Scoliosis can cause unevenness in the body (one shoulder or hip may be higher than the other) and difficulty walking.
-Treatments vary based on the severity of the curvature. Typical treatments include a brace to wear and in severe cases, surgery.
My first name is Nonkeratinized. My middle name is Squamous.

1. Which of the following vertebrae pivots to turn the head?
A. C1
B. C2
C. T1
D. T2

Joe is a handyman at work around town. One day he is helping his neighbor move boxes from a truck to their house. There are three boxes on the ground. Joe picks up the 1st box pretty easily, carrying it into the house. The 2nd box is more difficult, he tries to pick it up but can't. Joe succeeds to pick up the 3rd box but halfway to the house, the box becomes too heavy and he has to place it down.
2. Name the type(s) of contraction(s) that are involved in each box.

3. What do the lamellated corpuscles in the skin sense?
My first name is Nonkeratinized. My middle name is Squamous.

1. B
2. 1st box: isotonic; 2nd box: isometric; 3rd box: isotonic & isometric (after box becomes too hard to carry)
3. Uhhhhh... pressure and vibration????
