below or under.
Acromion process
Hook on the top of the scapula
Coracoid process
Anterior hook on the scapula
Infraglenoid and supraglenoid tubercle
Tubercles on the posterior surface of the scapula, just medial to the acromion.
Deltoid tuberosity
Tuberosity on the lateral humerus, about one third of the way down.
Olecranon fossa
Groove in the distal humerus where it articulates with the ulna.
Bones on the vertebral column
26 total, 7C, 12T, 5L, 1S, 1Co
Bones in the fetal vertebral column
33 or 34
Components of a typical vertebra
A vertebral foramen, a vertebral body, 2 transverse processes and a spinous process.
C1 vertebra
Called the atlas. Lacks a body, pedicles and lamina. Holds up the skull and pivots on top of the odontoid process of C2.
C2 vertebra
Called the axis. Has a thick, bifurcated spinous process. Has an odontoid process which protrudes superiorly and articulates with C1.
C7 vertebra
Has an extra long spinous process.
Thoracic vertebrae
Have demifacets on the body and transverse processes to articulate with the ribs.
Root of the spine of the scapula
Medial edge of the scapula spine.
Tubercles of the humerus
Greater and lesser. The greater tubercle is more posterior/lateral.
Intertubercular groove
The groove found between the greater and lesser tubercles of the humerus.
Olecranon process
End of the ulna. Forms that bump on the end of the elbow. Articulates with the distal humerus.
Head of the radius
Proximal end of the radius.
Styloid process of the radius
Distal end of the radius. Found in the wrist, just proximal to the thumb.
Dorsal/Lister’s tubercle
Tubercle on the posterior, distal radius.
Styloid process of the ulna
Distal, posterior ulna. Found in the lateral wrist.
Trigger point
Focal area of hyperirritability that is locally sensitive to pressure and can refer symptoms to other areas.
Active trigger point
Trigger points that cause local or reffered pain even when not compressed.
Latent trigger point
Trigger points that cause local or reffered pain only when compressed. Often develop into active trigger points.
Dysfunctional endplate hypothesis
Due to frequent stimulation, the motor endplate of the muscle fiber accumulates acetylcholine, resulting in sustained partial depolarization. Increases demand and causes depletion of ATP.
Results of trigger points
Causes the muscle to resist stretching and reduce the range of motion.
Jump sign
An involontary reaction to stimulation of a tender area.
Trigger point treatment options
Repetitive stripping, intermittent compression and prolonged ischemic compression.
What must be done after treating a trigger point?
Flushing via effleurage.
Components of the central nervous system
CSF, Meninges, brain and spinal cord
Components of the brain
Cerebellum, diencephalon, cerebrum, brain stem
Divisions of the peripheral nervous sytem
Autonomic and somatic
Divisions of the autonomic nervous system
Parasympathetic and sympathetic
Nerves of the peripheral nervous system
12 pairs of cranial nerves and 31 pairs of spinal nerves.
Myelin
White, fatty layer that surround axons and prevents signal depletion.
Nodes of Ranvier
Gaps in the myelin sheath that allow for faster transmission.
Efferent nerves serve what function?
Motor
Afferent nerves serve what function?
Sensory
Spinal cord root accronyms
SAD MEV (Sensory, afferent, dorsal - motor, efferent, ventral)
Functional unit of the nervous system
The reflex acr.
Trigger points are a result of what?
A pathological reflex arc.
