🗑

||||
| how were muscles named in early history and why was this a problem? what was the solution to this? | early anatomists named the muscles they saw in their native languages. this caused confusion.so, in 1895, a system of Latin names was developed
🗑
|
||||
| origin | muscle attachment at the relatively stationary end
🗑
|
||||

| belly | thicker middle portion of the muscle
🗑
|
||||
| tendon | muscle to bone
🗑
|
||||
| ligament | bone to bone
🗑
|
||||
| aponeuroisis | a white, flattened tendinous expansion (sheath of tendon)
🗑
|
||||
| dissect | separate muscles cleanly from adjacent muscles
🗑
|
||||
| transect | cut a muscle in half (mid-belly)
🗑
|
||||
| synergist | muscles that work together to cause movement
🗑
|
||||
| example of synergist? | the risorius and zygomaticus major, both work together for smiling
🗑
|
||||
| antagonist | muscles that work in opposition to eachother
🗑
|
||||
| example of antagonist | biceps brachii and triceps brachii
🗑
|
||||
| fixator | stabilizess joints as other movements go on
🗑
|
||||
| example of fixator | your trapezius muscles around scapula stabilize or "fixing" shoulder while you pic up pen
🗑
|
||||
| what are four muscle shapes? | circular, fusiform, convergent (triangular) and straight (parallel)
🗑
|
||||
| example of circular muscle? | orbicularis oculi
🗑
|
||||
| example of fusiform muscle? | biceps brachii
🗑
|
||||
| example of convergent (triangular) muscle? | temporalis, or pectoralis major
🗑
|
||||
| example of straight (parallel) muscle? | rectus abdominus
🗑
|
||||
| draw a circular muscle | just draw successive circles on top of eachother like the orbicularis oculi
🗑
|
||||
| draw a fusiform muscle | draw a bicep w thicker belly and scribbles in it
🗑
|
||||
| draw a convergent muscle | fibers fans together to a point, point kind of continues, looks like a broom kinda
🗑
|
||||
| draw straight muscle | draw parallel fibers, three groups with space for tendinous insertion
🗑
|
||||
| example of muscle naed for its location?/ | brachialis (in the arm)
🗑
|
||||
| example of muscle named for its shape? | teres minor (round)
🗑
|
||||
| example of muscle named for its origin and insertion? | sternocleidomastoid (sternum--< clavicle --> masstoid process of temporal bone
🗑
|
||||
| example of muscle named for the number of heads? | biceps brachii
🗑
|
||||
| trapezius | extends the head & neck
stabilizes, elevates, depresses and retracts the scapula
🗑
|
||||
| extends the head & neck stabilizes, elevates, depresses and retracts the scapula | trapezius
🗑
|
||||
| draw the trapezius | start at occipital, go to spine of scapula. continue midway thru vertebrae and all the way down to 3rd to last thoracic. fibers fan into scapula from above and belo
🗑
|
||||
| sternocleidomastoid | contract both sides = head flexion
contract one side: draws head down (and tilts it) to the side opposite of contracting muscle
helps to rotate the head
🗑
|
||||
| contract both sides = head flexion contract one side: draws head down (and tilts it) to the side opposite of contracting muscle helps to rotate the head | sternocleidomastoid
🗑

|
||||
| pull ear forward | auricularis anterior
🗑

🗑
|
||||
| pull ear back | auricularis posterior
🗑
|
||||
