Elizabeth T Malde Ch. 2


What are the three characteristics of good physical movement as described in the opening paragraphs of chapter 2? (11) graceful, buoyant, and balanced movement
Singing always requires _movement_.  (12)
What words does the author suggest might be substituted for posture? balance, buoyant, and springy (12)

What are the questions you should ask to map your skeleton? How large is my skeleton?  Where is my skeleton located?  What is the construction of my skeleton?  What is the function of my skeleton?  How does my skeleton move? (12)

What is the function of your skeleton? To serve as a structure of support, weight distribution, and movement. (14)

What is a joint? A location in your body where two bones connect. (14)

What is co-contraction? Trying to move by contracting both muscles simultaneously (14)

What would cause a skeletal muscle to not be able to move freely? It’s reciprocal muscle not staying relatively inactive, or released. (14)

What is the difference in the workings of a tense and a released muscle? A tense muscle does not move freely.  A released muscle moves with ease and efficiency.  A released muscle uses the appropriate amount of energy to complete the task. (15)

Our muscles should                   release                  and                  rest                  upon the skeleton. (15)

Describe the location of the 4 different portions of your spine.  What is the function of each? The cervical spine is comprised of the firs 7 vertabrae, from you’re A-O joint to the base of the neck.  The next 12 vertbrae make up the thoracic spine, and the last 5 vertebrae make up the lumbar spine.  The end of the spine is the sacrum and the coccyx (near the tailbone and pelvis)  (16)

What is the name of the top vertebra? atlas (16)

How does the thickness and size of the vertebrae differ? They get thicker and wider in circumference as you go down the spine. (19)

How far from your back is the lumber spine located? The lumbar spine is halfway between the front and back of the body. (19)

How much space does the circumference of your spine occupy? That depends on the section of the spine we’re talking about… (19)

What are the four curves of the spine?  How many vertebrae make up each curve?  In which direction do they curve? (19) The cervical curve is at the top, comprised of the cervical vertebrae, and it curves towards the back  Then the thoracic curve, 12 thoracic vertebrae, curving towards the front.  Then the lumbar curve, the 5 lumbar vertebrae, curving toward the back again.  Lastly, the sacral-coccygeal curve curve sharply towards the front. 

Which part of the spine is weight-bearing (front or back)?  What is the function of the other part? The front part of the spine bears the weight of the body, and the spinal processes in the back allow the vertebrae to connect to each other and attach to ribs. (19)

What are the three functions of your spinal vertebrae? To bear and deliver weight, to protect the spinal cord, and to allow movement. (19)

What are the three parts of each vertebra? What is the function of each?  The vertebral body (bear the body’s weight), the foraman (the opening for the spinal cord), and the spinal process (allows the vertebrae to connect with each other.  (19-20)

Describe the facets on the vertebrae? Small gliding joints that allow the spine to be both flexible and stable. (22)

Describe the front of the spine. The front is made up of the vertebral body, and they are located deep inside the body.  (22)

Describe the form and function of your vertebral discs. flat, circular, and about ¼ inch thick.  They have a hydraulic nature so they can compress when bearing weight and spring back into shape when the weight is removed. (22)

Where is the one place in the spine where there is no disc? There is no disc between the atlas and the axis (first two cervical vertebrae) (22)

What do singers need to avoid?  (22)

Describe the vertebral ligaments? Ligaments are strong yet flexible fibrous bands of tissue connecting bone to bone, and in this case vertebrae to vertebrae. (23)
                 
What is a tendon?  What is its function? A tendon is similar to a ligament, but connects muscle to bone.  (23)

What is fascia?  What is its function? Thin, strong connective tissue. (23)

Where are the six places of balance?
A-O joint
Arm structure
Thorax in relationship to lumbar spine
Hip joints
knee joints
ankle joints

Which of these six places of balance is not an actual joint? The thorax area.

What is the function of your atlas? Supports the weight of your head and distributes the weight to the rest of the spine. 

Explain how the skull and the atlas fit together. The two occipital condyles (little processes at the bottom of the skull) fit into depressions in the atlas.

Why is mapping your A-O joint important? “balance at the A-O joint allows the muscles in your neck and the rest of your body to release, thus allowing you to move easily and expressively while you sing.”

Where is you’re A-O joint located? Right in between your ears.

What is meant by a neutral position for the neck? this means a balanced relationship between the A-O joint and the rest of our body.  It’s not really a position, because that implies stasis, which is not good.

What are two ways to help find the accurate relationship between your thorax and your lumbar spine?
1. Lie down on the floor with your knees bent and feet flat on the floor
2. Walk backwards.                 

What is the function of the pelvis? It is designed to distribute the weight of the upper body to your legs. 

Describe your pelvis. The pelvis contains two bones on either side that mirror each other.  The top of the pelvis is called the iliac crest.  Between the two pelvic bones lies your sacrum, comprised of five fused vertebrae.  The upper part of the sacrum connects to the lowest lumbar vertebrae. The sacrum curves deeply back, increasing the depth of the pelvic cavity

What do you know about your hip joints? Connects the thigh bones to the pelvis via a neck angling towards the pelvis.  The hip joints are located outside the pelvis.  The hip joint is deep inside the body

What is your torso? It begins at the atlas and continues down all the way to the sit bones.  It’s huge!
                 
Describe your knee joint. Connects the thigh bone to the other bone, and is located behind and slightly below the kneecap. 
                 
Where is your kneecap located?

What are the three conditions of the knee joint? Bent, locked, or balanced.

How does the position of the thorax affect the knee joint? If your thorax is too far back in relation to your lumbar spine, the knee joints will lock to protect you from falling over. 

Do your knees need to bend in order to be balanced? No, the thorax just needs to be in balance.

Describe your ankle joint. The ankle joint is located where your two lower leg bones meet the talus bone of your foot (which lies on top of the heel bone.) 
                 
What are the bumps on the outside and inside of your ankle? Those bumps are the bottom of the two leg bones.

Which of the lower leg bones distributes our weight? The larger leg bone, the tibia (which bumps on the inside)

Which other joint in the body has a direct impact on the ankle joint? thorax (which isn’t really a joint, but we’ll go with it.)

How does the position of the thorax affect the ankle joint? The ankle joints will stiffen if the thorax is not balanced in relation to the lumbar spine, a fluid free movement will not be available to you.

In what order should we balance our joints? Start at the A-O joint and go downward.

Describe the location of the heel bone. It extends farther back from the line of balance, behind the ankle joint.

Describe your foot. The foot has three areas of balance, forming a tripod of weight distribution.   The toes aren’t one of them! 

Describe the structure of each arm. Comprised of collarbone, shoulder blade, upper arm bone, two lower arm bones, a wrist, and hand.  Four arm joints are sternoclavicular, upper arm, elbow, and wrist.

Name and describe the arm joints.


Describe position of collarbones and shoulder blades and how arm structure should be balanced.  The structure of your collarbones and shoulder blades, known as the shoulder girdle, is designed to center over your weight-bearing spine, with your collarbones roughly parallel to the ground.  The arm structure needs to balance lightly and centrally over your ribs. 

Your skeleton will be                   better balanced                  when your muscles are not                   being recruited to do the work of the skeleton                  .

My spine and my postural muscles that surround it ­­support my front and my back, freeing my front and my back for expressive movement.

What are the five poor postural instructions given at the end of the chapter?
1. Stand against the wall to achieve good posture
2. Stand “straight” as if the spine were a straight, solid broomstick
3. Lift the sternum high
4. Roll the shoulders back and/or hold them down
5. Tuck the pelvis under
6. Suspend your head by an invisible string from the ceiling.
