Lecture 2 Flashcards
Projections that are sites of muscle/ligament attachment
- tuberosity
- crest
- trochanter
- line
- tubercle
- epicondyle
- spine
- process
Projections that help form joints
- head
- facet
- condyle
- ramus
depressions/openings for blood vessels/nerves
- meatus
- sinus
- fossa
- groove
- fissure
- foramen
Tuberosity defenition
large rounded projection
Crest defenition
narrow ridge of bone, prominent
Trochanter defenition
very large, blunt, irregularly shaped process
Line
narrow ridge of bone, less prominent than a crest
Tubercle defenition
small rounded projection or process
epicondyle defenition
raised area on or above a condyle
spine defenition
sharp, slender, pointed projection
process defenition
any bony prominence
Head defenition
bony expansion carried on a narrow neck
Facet defenition
smooth, nearly flat surface
Condyle defenition
rounded articular projection
Ramus defenition
armlike bar of bone
Meatus defenition
canal like passageway
Sinus defenition
cavity within a bone filled with air and lined with membrane
Fossa defenition
shallow, depression in a bone
Groove defenition
furrow
Fissure defenition
narrow, slit like opening
Foramen defenition
round or oval opening through a bone
Endochondral Ossification
replacement of cartilage with bone due to avascular properties that are outpaced by growth and leads to lack of oxygen
6 weeks to 25 y/o
Synarthrosis Joints
are fibrous joints that are immovable
Amphiarthrosis Joints
are cartilaginous joints that are slightly moveable
Diarthrosis Joints
synovial joints that are moveable
Synarthrosis joints types
- skull sutures
- syndesmoses - depends on fibre length
- gomphoses - teeth
Amphiarthrosis Joints types
- synchondroses - united by hyaline cartilage
- symphyses - united by fibrocartilage
- primary amphiarthroses - replaced by bone
- secondary amphiarthroses - cartilaginous 4evr
Diarthroses Joint types
specialized for mobility, enclosed in a joint capsule, lined by a sereous membrane producing synovial fluid
Origin
does not move during contraction
Insertion
moves towards the origin during contrsction
Muscle injury location
at the myotendinous junction (MTJ)
Cervicle Plexus
nexk and throat
Brachial Plexus
pectoral girdle and upper limb
Lumbar plexus
anterior hips and thigh
Sacral plexus
glutes, posterior thigh, leg
Spinal cord ending
L1/L2
Dorsal root ganglion contain
sensory neurons
Ventral root contains
motor neurons
Spinal nerves contents
contain both sensory and motor axons
Paralysis
loss of function in a muscle or loss of a movement
Numbness
loss of sensation
Weakness/paresis
partial loss of function of muscle/movement
Paresthesia
partial loss of sensation
