Q

What are the muscles responsible for flexion at the cervical region?

A

Longus cervicis + scalenus anterior + sternocleidomastoid muscles

17
Q

What are the muscles responsible for lateral flexion of the cervical region?

A

The scalenus anterior and medius + the trapezius + the srenocleidomasoid muscles

18
Q

What are the muscles responsible for rotation of the cervical region?

A

The sternocleidomastoid on one side + the splenium on other side

19
Q

Describe the origin and insertion of sternocleidomastoid muscle?

A

From: the manubrium sterni and medial third of clavicle.
To: mastoid process and occipital bone.

20
Q

A patient complains of inability to flex, extend and rotate his neck. What is the muscle affected? And what is the nerve supply of this muscle?

A

The sternocleidomastoid muscle, supplied by spinal part of accessory nerve and C2+3

21
Q

A muscle originate from the deep facia of the temporalis major and the deltoid and inserted on the body of mandible and angle of mouth.

A

The platysma muscle

22
Q

What is the action of platysma muscle?

A

Depresses the mandible and angle of the mouth

23
Q

List three muscles which contribute in depressing the mandible?

A

The platysma, the posterior belly of digastric and the mylohyoid

24
Q

What is the difference between the origin of anterior and posterior belly of digastric?

A

Anterior belly: from the body of mandible.

Posterior belly: from the mastoid process.

25
Q

What is the nerve supply of the digastric muscles?

A

The facial nerve

26
Q

Originate from the styloid process to the body of hyoid bone. It elevates hyoid bone.

A

The stylohyoid muscle

27
Q

What is the nerve supply of the mylohyoid muscle? And what is the action of it?

A

The inferior alveolar nerve.

It elevates floor of the mouth and depresses mandible

28
Q

What is the nerve supply of sternohyoid and sternothyroid muscles?

A

The ansa cervicalis; C1,2,3

29
Q

What muscles do first cervical nerve supply?

A

The geniohyoid and the thyrohyoid muscles

30
Q

What is the action of sternothyroid muscle?

A

Depresses the larynx

31
Q

What is the origin of scalenus anterior muscle?

A

Transverse processes of third, fourth, fifth and sixth cervical vertebrae

32
Q

What are the relations of scalenus anterior muscle?

A

Anteriorly: carotid artery, vagus nerve, internal jugular vein and the deep cervical lymph nodes.
Posteriorly: the pleura, the origin of brachial plexus and the 2nd part of subclavian artery.
Medially: the vertebral artery and vein and the sympathetic trunk. On the left side the medial border is related to the thoracic duct.
Laterally: branches of the cervical plexus, the roots of the brachial plexus and the 3rd part of the subclavian artery.

33
Q

The carotid sheath, the investing layer, the pretracheal layer, and the prevertebral layer are all formed from the condensation of this cervical fascia.

A

The deep cervical fascia

34
Q

A condensation of the deep cervical fascia surrounding the trapezius and the sternocleidomastoid muscles.

A

The investing layer

35
Q

A layer of the deep cervical fascia that surrounds the thyroid and the parathyroid glands.

A

The pretracheal layer

36
Q

A layer of the deep cervical fascia that forms the axillary sheath.

A

The prevertebral layer

37
Q

What are the contents of the carotid sheath?

A
  • The common and the internal carotid arteries.
  • The internal jugular vein.
  • The vagus nerve.
  • The deep cervical lymph nodes.
38
Q

What are the subdivisions of the anterior triangle?

A

The Carotid triangle - the muscular triangle - the digastric triangle - the submental triangle

39
Q

By which muscle does the posterior triangle is subdivided into large occipital and small supraclavicular triangles?

A

The inferior belly of omohyoid muscle
