QUESTIONS AND SOLUTIONS RATED A+
✔✔cochlea - ✔✔a coiled, bony, fluid-filled tube in the inner ear; sound waves traveling
through the cochlear fluid trigger nerve impulses
✔✔Pivot joint - ✔✔Rotation, atlas axis joint
✔✔Saddle joint - ✔✔Thumb
✔✔Gliding joint - ✔✔Wrist and ankle joints
✔✔Cranial vault - ✔✔Surrounds and protects the upper portion of the brain
✔✔cribriform plate - ✔✔The horizontal plate of the ethmoid bone separating the cranial
cavity from the nasal cavity.
✔✔Hard plate - ✔✔the bony structure that forms the roof of the mouth and separates
the mouth from the nasal cavities
✔✔Sinuses - ✔✔Cavities formed by the cranial bone
✔✔Paranasal sinuses - ✔✔air-filled cavities lined with mucous membrane, located in
the bones of the skull
✔✔Hyoid bone - ✔✔a U-shaped bone in the neck that supports the tongue.
✔✔cricothyroid membrane - ✔✔Soft depression made up out of a thin sheet of
connective tissue, connects the thyroid to the cricoid
✔✔Larynx - ✔✔voice box
✔✔Vertebral column - ✔✔7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar
vertebrae, 5 sacrum, 4 coccyx
✔✔Sacroiliac joints - ✔✔Where the sacrum is joined to the iliac bones, forms the pelvis
✔✔Superasternal notch - ✔✔Space superior to the manubrium
✔✔Angle of Louis - ✔✔the junction between the body of the sternum and the
manubrium; the starting point for locating the ribs anteriorly
✔✔Acromion process - ✔✔Protects the shoulder joint
, ✔✔Plexuses - ✔✔Areas where the spinal nerves come together and transmit their
impulses to areas of the body through a common nerve
✔✔Acetabulum - ✔✔the cup-shaped hollow in the hipbone into which the head of the
femur fits to form a ball-and-socket joint
✔✔Calcaneus - ✔✔heel bone; largest of the tarsal bones
✔✔Excitability - ✔✔The ability to receive and respond to a stimulus
✔✔Contractibility - ✔✔ability to shorten
✔✔Extensibility - ✔✔ability to be stretched
✔✔Elasticity - ✔✔The ability of a material to bounce back after being disturbed
✔✔Origin of of skeletal muscle - ✔✔Fastened to a immovable part at a moveable joint
✔✔Insertion - ✔✔Connects moves me part on other side of the joint, pulled to the origin
✔✔Four types of protein that make up myofilaments - ✔✔Actin, myosin, troponin,
tropomyosin
✔✔Actin - ✔✔A globular protein that links into chains, two of which twist helically about
each other, forming microfilaments in muscle and other contractile elements in cells.
✔✔Myosin - ✔✔The contractile protein that makes up the thick filaments of muscle
fibers
✔✔Troponin - ✔✔regulatory protein that binds to actin, tropomyosin, and calcium
✔✔Tropomyosin - ✔✔A protein of muscle that forms a complex with troponin regulating
the interaction of actin and myosin in muscular contraction
✔✔Titin - ✔✔a protein that positions the myosin filament to maintain equal spacing
between actin filaments
✔✔Motor nerve - ✔✔carries messages away from the brain and spinal cord to muscles
and organs; efferent nerves
✔✔neuromuscular junction - ✔✔point of contact between a motor neuron and a skeletal
muscle cell
