Flashcards in Spinal Ex 3 Wk 1 Deck (30):
1

What is the insertion for the iliocostalis lumborum pars lumborum?

Iliac crest of the in nominate bone 92

2

What osseous parts of the vertebral column serve as an origin to the iliocostalis thoracis?

None

3

What is the vertebral column origin for the longissimus thoracis lumborum?

Accessory process & medial part of transverse process of L1-L5

4

Which erector spinal muscles attach to cervical articular processes?

Longissimus cervicis & longissimus capitis

5

The semispinalis capitis and spinalis capitis may fuse to form what muscle?

Biventer cervicis

6

Which transverse spinalis muscle attaches to articular and mammillary processes along the spine?

Multifidis

7

The multifidis cervicis participates in what movements?

Alters the zigapophyseal capsular ligament in response to load distribution. Determines the cervical spine response to injury as evidenced by neck pain. Is a significant contributor to postural control of the head and neck.

8

Which muscles of the spine exhibit a reversal of the expected origin - insertion combination?

Iliocostalis lumborum pars lumborum, longissimus thoracic lumborum and multifidis lumborum.

9

Rotator muscles are typically identified in what region of the spine?

Thoracic

10

Which us occipital muscle lacks an attachment to the skull?

Obliquus capitis inferior

11

What is the proposed function of the suboccipital muscle group?

Postural stabilizers of the atlanto-occipital and atlanto-axial joints.

12

What is the innervation of each part of the cervical intertransversarii?

Anterior belly, cervical inttransversarii ->Ventral ramus, cervical spinal nerve
Posterior lateral belly, cervical intertransversarii ->Ventral ramus, cervical spinal nerve
Posterior medial belly, cervical intertransversarii -> Dorsal ramus, cervical spinal nerve

13

What is the innervation of each part of the lumber intertransversarii?

Medial belly, lumbar intertransversarii -> dorsal ramus, lumbar spinal nerve
Anterior lateral belly, lumbar intertransversarii -> ventral ramus, lumbar spinal nerve
Posterior lateral belly, lumbar intertransversarii -> ventral ramus, lumbar spinal nerve

14

Which muscle group is innervated by both dorsal rami and ventral rami of spinal serves?

Intertransversarii.

15

Based on the density of muscle spindles what is the proposed function of the intertransversarii?

Acts as a propioception transducer in conjunction with interspinalis to coordinate the smooth movement of the spine and to maintain appropriate posture.

16

Which muscle is said to form the iliolumbar ligament?

Quadratus lumborum.

17

Identify all muscle groups innervated by dorsal primary rami branch patterns.

Splenius, erector spinae, transversospinalis, suboccipital, interspinalis, levator costarum, and intertransvsarii.

18

Based on manner of action, define neurotransmitter.

A neural active substance acting rapidly and locally on a target cell.

19

What are the basic morphological of neurons?

Unipolar, bipolar, pseudounipolar, and multipolar neurons.

20

What are the possible locations of bipolar neurons?

The nasal olfactory epithelium, the retina, the vestibular or Scarpa's ganglion, and the cochlear or spiral ganglion.

21

What part of the vertebra forms the eye of the Scotty Dog?

Pedicle

22

What part of the vertebra forms the nose of the Scotty Dog?

Transverse process

23

What part of the vertebra forms the ear of the Scotty Dog?

Superior articular process

24

What part of the vertebra forms the front leg of the Scotty Dog?

Inferior articular process

25

What part of the vertebra forms the neck of the Scotty Dog?

Pars interarticularis

26

On a x-ray, what is the cause of the black regions over the cervicals?

Air

27

What is specifically measured in a lateral occiput-C2 x-ray?

Atlanto-dental interspace

28

What bony density accounts for the back of an IVF in an oblique cervical x-ray?

Posterior tubercle

29

What forms the eye of the Scotty Dog in A-P thoracic x-ray?

Pedicle

30

What is the suspected cause of the black regions in A-P x-ray of the pelvis? Be specific

Gas in intestines
