Spine and Thorax Flashcards
This muscle is responsible for hiccups basically spasms
Diaphragm
Name the three holes of the Diaphragm
And what are they for?
Abdominal Aorta, Vena Cava Foramen and Esophageal hiatus
Abdominal Aorta-away,
Attachment site for the diaphragm
Central Tendon
nerve that feeds the diaphragm
Phrenic Nerve
involuntary contraction of the diaphragm will cause air to rush into the lungs and vocal cords to shut results in a
hiccup
muscles between the ribs,meat on the ribs
stabilizes rib cage, assist in respiration
intercostals
known as the the hip hiker muscle
deepest muscle of the abdomen ; watch the kidneys
originates at the posterior iliac crest inserts 12th rib and transverse process
accessible and workable on the lateral edge
Quadratus Lumborum
known as the anatomical weight belt
Transverse abdominus p.211
superficial of the spine
runs from the sacrum to the occiput along the posterior aspect of the vertebral column
includes iliocostalis, longissimus and spinalis(Lateral–>Medial)
I love sphaghetti
Erector Spinae Group
responsible for rotation of the trunk
Obliques
superficial to the erectors
where splenius capitus attaches at
finlike sheet of connective tissue that runs along the sagittal plane
help stabilize head and neck
Ligamentum Nuchae
deep to the trapezius and rhomboids
deep to the splenius capitis
splenius capitis
splenius cervicis
deep to the erector spinae muscle group
composed of three branches multifidi, rotatores and semispinalis
Transversospinalis Group
Located between the spinous and transverse processes and progress down the spine and transverse but now borders are palpable.
lamina groove
forms the speed bumps seen on the neck when extended
located along the thoracic and cervical vertebrae
semispinalis capitis
accessible in lumbar spine, ONLY muscles with fibers that lie across the posterior surface of the sacrum
trouble makers
Multifidi
shorter, smaller lie deep to the multifidi (troublemakers)
Rotatores
A: to rotate and extend the vertebral column
O:sacrum and transverse processes
I: Spinous processes of lumbar vertebra 2-4 vertebrae
Multifidi
A: to rotate and extend the vertebral column
O: Transverse processes of lumbar through cervical vertebrae
I: spinous process of lumbar vertebrae 1-2
Rotatores
smallest of the erector spinae group and lies closest to the spine in the lamina groove
Only one attaches to the spinous process
spinalis
assist in extension,lateral flexion, and rotation of the head and neck to the same side
longissiumus and iliocostalis
broad, flat tendon stretching across the thorax and lumbar regions
anchor for several muscles
Thoracolumbar Aponeurosis
Known as the Atlas
C1
Known as the Axis
C2
Total number of vertebrae
24
Number of Thoracic Vertebrae
12
How many cervical vertebrae
7
How many lumbar vertebrae
5
Mean to bent backwards
Lordosis
Curved, bent
Kyphosis
State the order the spine curves
Cervical Lordosis,Thoracic Kyphosis, Lumbar Lordosis, Sacral Kyphosis
Posterior bony process
Spinous process
Sheet like area in abdominal area
Abdominal Aponeurosis
White line area
Lina Alba
Name the breathing muscles
Serratus posterior/superior and inferior, diaphragm, intercostal so, ql to assist
Neck is flexed spinous process of c7 flexes
Superiorly
Shorter lay laterally
Palpable deep to erector spine
Thoracic Processes
The transversespinalis muscles (rotators, multifidi, and semispinalis) are located where
Lamina Groove
Erector Spinae muscles (spinalis, longissimus and iliocostalis) extends from
Tip of the spinous process to the body
Flexion/Extension of the Vertebral Column are done in what plane
Sagittal
Rotation of the Vertebral Column done in what plane
Transverse
Lateral Flexion of the vertebral column happens in what plane
Frontal/Coronal Plane
Elevation/Expansion mainly inhalation
Deperession/Collapse mainly exhalation
Found in what plane
Sagittal
Shorter part of the vertebrae lay outer
Transverse Process
