#1?

Vertebral body of the lumbar spine

2?

Vetebral foramen of lumbar spine

3?

Transverse process of lumbar spine

4?

Spinous process of lumbar spine

Sequence the vertebral regions from superior to inferior.

Cervical → Thoracic → Lumbar → Sacrum

How many vertebrae are in the Cervical, Thoracic, and Lumbar regions respectively?

7 Cervical, 12 Thoracic, 5 Lumbar (7, 12, 5)

What are the three unique identifying features of cervical vertebrae

Bifid spinous processes, transverse foramina, and triangular vertebral foramina

Which specific vertebra is known as the “Atlas”

C1

Which vertebra features the “dens”(odontoid process)

C2 (The Axis)

What type of a joint is the Atlantoamxial Joint, and what movement does it allow?

Piviot joint, it allows for rotation (the “no” motion)

What is the primary function of the lumbar vertebrae

Weight-bearing of the torso

Which region of verebrae is the only one to feature costal (demi) facets for rib articulation.

Thoracic vertebrae

What are the true ribs

Ribs 1-7

What are the false ribs?

Ribs 8-10

Why are the floating ribs

Ribs 11-12

Why are ribs 1-7 classified as “True Ribs”

Because each has its own costal cartilage that connects directly to sternum.

How do “False Ribs” (8-10) attach to the sternum

Their costal cartilages join the cartilage of rib 7

Why are ribs 11-12 called “floating ribs”

They have no anterior attachment to the sternum or other ribs

Which three bones fuse together to form the Os Coxae (Hip bone) and the acetabulum

Ilium, ischium, and Pubis

What is the scientific name for the hip joint

Acetabulofemoral joint

How is the hip joint classified by structure

Ball and socket joint

What is the primary mechanical function of the hip joint

To support body weight in static and dynamic postures

Which landmark is known as the “sit bones” because it supports weight when seated

Ischial Tuberosity

Which landmark is the superior rim of the illium and key palpitation point

Iliac Crest

What is the strongest ligament in the body

Iliofemoral ligament (Y Ligament)

Which ligament originates from the ischium and spirals to limit medial rotation

Ischiofemoral ligament

List the four abdominal muscles from superficial to deep

External Oblique (Superficial), Internal Oblique & Rectus Abdominis (Intermediate), Transverse Abdominis (Deep).

Which muscle is referred to as the “natural corset” because it stabilizes the spine and compresses contents without moving the trunk

Transverse abdominis

What are the three columns of the erector spinae group lateral to medial.

Iliocostalis, Longissimus, and Spinalis ("I Love Spinach")

In which plane of motion do Flexion and Extention occur

Sagittal plane

In which plane of motion does lateral flexion (side bending) occur

Frontal (Coronal) Plane

Rotation occurs around which axis

Vertical Axis

If a patient can bend forward but cannot rotate their head, which specific joint is likely restricted

Atlantoaxial Joint

Which muscle is the primary “powerhouse” for climbing stairs or rising from a chair

Gluteus Maximus

Which muscle is responsible for "hip hiking" when standing on one leg?

Quadratus Lumborum.
