Practical Exam 1 Flashcards
External Occipital Protuberance
Bump at the back skull
Page 6
Spinous Process of C7
Vertebra Prominens- Most prominent spinous process in the spinal column.
Page 6
Posterior Superior Iliac Crest
Back of/Top of the hip bones
Page 6
Scapula Acromion Spine Superior Angle Inferior Angle
- Acromion is the most superior and most lateral point of the scapula.
- Spine is the top edge of the scapula.
- Superior Angle is the most superior part of the most medial part of the scapula
- Inferior Angle is the most inferior part of the scapula and sticks out the most.
Page 6
Cervical Vertebrae
The first six vertebrae- Atlas, Axis, C1-C7
Smaller bodies, large vertebral formina, and short spinous processes with bifurcate tips.
Page 7
Thoracic Vertebrae
The middle twelve vertebrae- T1-T12
Middle sized body and spinous processes and angled transverse processes.
Page 7
Lumbar Vertebrae
The last five vertebrae that aren’t fused- L1-L5
Larger bodies, broad spinous processes, and straight transverse processes.

Iliac Crest
Top of the hip bones felt on the back
Page 6
Mastoid Process
Inferior and lateral edge of the skull near the mandible (Jaw)
Page 6
Sacrum
Sacral Foramina
Sacral Hiatus
- Sacral Foramina are the holes on either side of the middle of the fused vertebrae
- Sacral Hiatus is the opening into the vertebral canal on the midline sacrum right above the coccyx

Trapezius Superior Part Middle Part Inferior Part Nerve Blood Supply
- Superior Part: Attaches to lateral third of clavicle and elevates scapula
- Middle Part: Attaches to acromion and spine and retracts scapula
- Inferior Part: Attaches near the medial end of the spine of the scapula and depresses the scapula
- Nerve: Accessory Nerve
- Blood Supply: Transverse Cervical Artery

Latissimus Dorsi
Origin: T7-T12, Thoracolumbar Fascia, and the Iliac Crest
Insertion: Ribs 9-12 and Sulcus of the Humerus
Nerve: Thoracodorsal Nerve
Blood Supply: Thoracodorsal Artery
Page 10
Rhomboid Major
Origin: T2-T5
Insertion: Medial border of the scapula
Nerve: Dorsal Scapular Nerve
Blood Supply: Dorsal Scapular Artery/Vein
Page 10
Rhomboid Minor
Origin: C7-T1
Insertion: Medial border of the scapula
Nerve: Dorsal Scapular Nerve
Blood Supply: Dorsal Scapular Artery/Vein
Page 10
Triangle of Auscultation
Bordered by the Trapezius, Latissimus Dorsi, and the rhomboid major/scapula.
Good for listening to organs like the lungs
Page 10
Serratus Posterior Superior
Origin: Nuchal Ligament and C7-T3
Insertion: Superior borders of ribs 2-5
No picture- Very thin muscle under the Rhomboids
Serratus Posterior Inferior
Origin: T11-L2
Insertion: Inferior borders of ribs 9-12
No picture- Very thin muscle under the Latissimus Dorsi
Splenius Capitus
Origin: Nuchal Ligament, C7-T6
Insertion: Mastoid Process and Superior Nuchal Line
Page 13
Erector Spinae
Iliocostalis
Longissimus
Spinalis
Iliocostalis: Most lateral. From Ilium to superior attachments on ribs.
Longissimus: Middle Muscle. From Sacrum to transverse processes of cervical and thoracic vertebrae and mastoid process.
Spinalis: Most medial. From spinous processes to spinous process more superior.
Page 13
Semispinalis Capitis
Deep to Splenius Capitis. Greater occipital Nerve goes through it.
Origin: Transverse processes of the upper thoracic vertebrae
Insertion: Between superior and inferior nuchal line.
Page 13
Suboccipital Triangle
Obliquus Capitus Superior-Lateral- From Transverse process of atlas to between superior and inferior nuchal lines
Obliquus Capitis inferior-Bottom- From Spinous of C2 to Transverse of C1
Rectus Capitis Posterior Major- Medial Boundary- From Spinous of C2 to Inferior nuchal line.
Rectus Capitis Posterior Minor- Superior to Major- From Tubercle of C1 to Inferior nuchal line.
The Greater Occipital Nerve and the Vertebral Artery supply all of these muscles with innervation and blood. Suboccipital nerve and vertebral artery can be found in the Triangle. Greater Occipital passes over.

Ligamentum Flavium
“Yellow Ligament”- Connect Lamina of adjacent vertebrae to each other.
Epidural Space
Contains fat and veins. Between bones and Dural Sac
Page 19
Dura Mater
Outermost protective covering for the spinal cord
Page 18
Arachnoid Mater
The protective layer immediately deep to the Dura Mater
Page 18
Subarchnoid Space
The space between the Arachnoid Mater and the Pia Mater. Contains cerebrospinal fluid
Page 18
Pia Mater
The final, very thin protective layer on the spinal cord and can’t be dissected away.
