Vertebrae, Ribs and Sternum ect.

Note that for the vertebre have the same bone markings, so know them and know how the differentiate between vertebrae

C3-C7

C3-C7

These diagrams show C4 and C7 but really work for C3-C7. According to LAB TA you only need to know the names of C1 and C2 (atlas and axis, respectfully). Most terms (but not all are included from the wish list because I would have to find a new vertebre and I really don’t want to)

Superior articular surfaces

Most are bifid

Inferior Atricular surface

Body

Spinous Process

Long and angled

Transverse Process

Lateral Projections

transverse Foramina

Hole in transverse process

Vertebral foramen

Hole posterior to body

Pedicle

Connects body to transverse process

Lamina

Connect Transverse process to spinous process

Intervertebral foramina

Intervertebral Foramen

Small openings formed on the lateral side of the vertebral column, formed between 2 vertebra that are stacked on top of each other. Also permits spinal nerve to pass.

Intervertebral Foramen

Sacrum

5 fused vertebrae in one bone, name S1-S5

S1-S5

Ala

Wings, formed by fused transverse processes

Sacral Canal

Medial sacral crest

Formed by fused spinous processes

Medial Sacral Crest

Sacral foramina

Similar to intervertebral foramina

Coccyx

Often called the tailbone

Thoracic Vertebrae

12 bones named T1-T12

Thoracic Vertebrae

Looks like a giraffe, Jurassic, thoracic

Superior articular surfaces

Inferior Articular Process

*Articular facets for ribs (costal

facets)

On the transverse processes

Lumbar Vertebrae

Lumbar Vertebrae

Looks like a moose!

Ribs

True Ribs

Ribs 1-7 with individual costal cartilage

False Ribs

Ribs 1-7 with individual costal cartilage

Floating Ribs

Ribs 11-12 that do not attach to the sternum in any way

Head

(superior and inferior articular facets)

Posterior portion that articulates with thoracic vertebrae

Neck

Just lateral to head

Tubercle

Articulates with transverse process of thoracic vertebrae

Body/Shaft

Curved main part of rib

Sternum

Anterior in thorax and made of 3 parts

Sternum

Manubrium

Superior portion

Jugular Notch

Clavicular Notch

Facets for ribs

Sternal Angle

Transverse ridge on the anterior surface

Body

Lower 2/3 of bone, below sternal angle

Xiphoid process

Xiphoid process
