Posturing
This suture connects the parietal and temporal bones.
What is the squamous suture?
The glenoid cavity is part of this bone.
What is the scapula?
Only joints of this structural classification feature a joint cavity.
What is a synovial joint?
This is the functional unit of the skeletal muscle.
What is the sarcomere?
This class of ion channels opens only with the binding of a specific chemical, such as a neurotransmitter.
What are chemically gated (ligand-gated) ion channels?
This vertebra has no body.
What is the atlas (C1)?
Children are often told to keep this process off the table while eating.
What is the olecranon process?
When the sole of your foot is turned medially, this has occurred.
What is inversion?
This connective tissue surrounds the entire muscle.
What is the epimysium?
This enzyme breaks down the neurotransmitter ACh, ending the nervous stimulus.
What is acetylcholinesterase?
This is the superior portion of the sternum.
What is the manubrium?
The tibia transmits the weight of the body to this ankle bone via a direct articulation.
What is the talus?
This is the functional classification of the cranial sutures.
What is synarthrosis?
Thick filaments are found in this region of the striated myofibrils.
What are the A bands?
This ion stimulates the exocytosis of synaptic vesicles full of ACh.
What is Ca2+?
This nasal concha is a facial bone.
What is the inferior nasal concha?
The lateral malleolus is part of this bone.
What is the fibula?
Though not strictly part of the joint, these bags of fluid act as lubricating "ball bearings"
What are bursae or tendon sheaths?
Ca2+ ions bind to this regulatory protein, which will then change shape and move a different protein to reveal myosin-binding sites.
What is troponin?
A single stimulus causes a muscle twitch. Two or more stimuli received in rapid succession result in this.
What is wave (temporal) summation?
An abnormal dorsal thoracic curvature, common in those with osteoporosis.
What is kyphosis?
This bone is found on the lateral end of the distal row of carpal bones.
What is trapezium?
The three C's often damaged in a knee injury are the cartilages, the cruciate ligaments, and these.
What are the collateral ligaments?
ATP is required for this step of the cross bridge cycle.
What is cross bridge detachment?
During depolarization, these channels open, flooding the muscle fiber with an ion that triggers an action potential.
What are voltage-gated Na+ channels?
