Skeleton 1
These are the bones of the ankle?
What are tarsals?
Cervical, Thoracic, Lumbar, Sacral, Coccyx
What are the regions of the vertebral colum?
These are the classifications for joints
What are structural and functional? (fibrous/cartilaginous/synovial - synarthroses/amphiarthroses/diarthroses)
This is when a contraction is caused by a single brief stimulus
What is a twitch?
The endomysium surrounds this
What is the muscle fiber?
Long, short, flat, and irregular
What are the classifications of bones?
This includes the bones of the skull, spine, and rib cage?
What is the axial skeleton?
This is an example of a synarthrosis
Sutures of the skull
These are the muscles cells and contain these specialized organelles
What are muscle fibers and myofibrils?
This is the prime mover involved in breathing
What is the diaphragm?
This girdle provides more flexibility and motility than the other girdle
The last two pairs of these are only attached to posteriorly to the sternum
What are floating ribs?
These are the advantages of slightly movable joints
What are some flexibility while being very stable?
These are the three things muscles can do to increase the strength of their contraction
What are increase the frequency of motor neuron stimulus, increase the number of motor units, and increase the size of muscle fibers?
These two things are required for a muscle contraction to occur?
What is ATP and access to actin?
Stress is necessary for this process to occur
What is bone remodeling?
Osteocytes release signals that damage has occur, osteoclasts engage in resorption, Macrophages promote tissue remodeling, osteoblasts build new bone
What are the steps of bone remodeling?
These are the configurations of the synovial joint
What are hinge, gliding, pivot, condylar, saddle, and ball and socket?
This is the reason why muscles contribute to our thermoregulation?
What is they need a lot of ATP, which is produced from cellular respiration, which generates a lot of heat?
This is the reason muscles cells have a lot of mitochondria
What is because cellular respiration occurs in the mitochondria and muscles need a lot of ATP?
These are the 6 main functions of skeletal system
What are support, protection, movement storage, hematopoiesis, and hormone production?
The names of all the major bones of the shoulder, arms, and hands
What are clavicle, scapula, humerus, ulna, radius, carpals, metacarpals, and phalanges?
These things are require to generate movement
What is bones to act as levers, joints that muscles connect across, and muscles to generate force?
The names of the major muscles on the posterior side of the body
What are the trapezius, deltoid, latissimus dorsi, erector spinae, gluteus maximus
These are the steps of muscles contraction according to the sliding filament model
What is sarcomeres contract when the heads of myosin grab action and pull them to slide past each other causing the sarcomere to shorten?
