Femur
The bone-resorbing cells
Osteoclast
Carpal bone is part of this skeleton
Axial
Bone forming cells
osteoblast
tissue that contains intercalated disks
Cardiac muscle
muscle contraction with no change in length
The wrist bone is an example of this type of bone
Short bone
Moving the arm in a circle around the shoulder joint
Circumduction
number of bones in the human body (ish)
206
Connects a nerve fibre and the muscle it stimulates
neuromuscular junction
cervical, thoracic, lumbar, sacrum, coccyx
regions of the spine from top to bottom
The strong fibrous membrane covering the shaft of the long bone
periosteum
two bones of the lower arm
ulna and radius
bone at the back of the skull
occipital
dictate how much weight a muscle can lift
number of activated motor units
non voluntary muscle type
smooth
The hollow shaft of a long bone
diaphysis
Movement that increases the angle of a joint
extension
Location of metatarsals
the feet
The muscle attachment to the more movable bone
insertion
minimal level of stimulation required to cause a fibre to contract
threshold stimulus
needle like threads of spongy bone
Trabeculae
movement that reduces the angle of a joint
flexion
false ribs
rib pairs 8, 9, and 10 that attach to the costal cartilage of rib pair 7 and then to the sternum
These contraction move a muscle through a full range of motion and are very important for posture
Tonic contractions
this allows you to lift different weights with the same muscle
number of motor units used by the muscle
