This type of lever has the most mechanical advantage.
What is 2nd class levers?
This muscle is responsible for full closure of the eyes.
What is orbicularis oculi?
Neck flexion is created by the bilateral action of these small muscles attaching to the vertebral bodies and transverse processes of the cervical spine.
What is longus colli?
Facet joint innervation occurs at these levels.
What are at the level, above the level, and below the level?
The shape of these vertebrae have near vertical facets and long, sloping spinous processes.
What are thoracic?
These two motions occur simultaneously at the atlanto-occipital joint when nodding (flexing) your head.
What is anterior roll and posterior slide?
This muscle helps guide retraction of the articular disc during jaw closure.
What is the lateral pterygoid?
This group of muscles is often shortened as a result of forward head posture.
What is suboccipitals?
Loss of sensation over the back of the thumb indicates a potential problem with this spinal nerve.
What is C6?
This type of bone is better at resisting compressive forces.
What is cortical?
This arthrokinematic motion is the result of a single point contacting multiple points on the articulating surface.
What is slide?
This muscle results in abduction of the eyeball.
What is lateral rectus?
This structure is essential for force transmission in the spine and permits rocking type segmental movement like a ball bearing.
What is the nucleus pulposis?
This nerve branch runs through the superior orbital fissure before splitting into it's terminal branches.
What is opthalmic division of the trigeminal nerve?
This is the anatomical landmark that the tectorial membrane begins. Below that, it's called something else.
What is C2?
Contact of the spinous processes along with this structure limit extension in the lumbar spine.
What is the anterior longitudinal ligament?
This vital part of the brain houses the respiratory center, cardiovascular center, and swallowing center.
What is the medulla?
This is the most superficial of the major intrinsic muscles of the spine.
What is splenius?
This outlier is the lone pharynx muscle that is NOT innervated by the vagus nerve.
What is stylopharnygeus?
This type of connective tissue has a high proportion of type II collagen and distributes and absorbs compression forces and friction.
What is articular or hyaline cartilage?
During shoulder flexion, the clavicle elevates. These arthrokinematics at the sternoclavicular joint occur during that clavicular elevation.
What is superior roll and inferior slide?
This blood vessel supplies the medial surfaces of the cerebral hemispheres and the corpus callosum.
What is the anterior cerebral artery?
I innervate the serratus posterior superior and inferior muscles.
What are ventral rami or intercostal nerves?
The root of the tongue is innervated by this nerve.
What is the vagus nerve?
This fiber type is responsible for transmission of dull, aching pain and is often poorly localized with a slow conduction velocity.
What are C fibers?
