Anatomy Year 2 - Head, Neck and Back

1

Regio Scapularis is a back region

1

The anterior rami of C1 through C4 take part in the formation of cervical plexus.

1

The boundaries between the thoracic region and the back are the anterior axillary lines

1

Sternocleidomastoid is a superficial muscle of the back.

1

M.latissimus dorsi is a powerful extensor of the arm

1

Superficial muscles of the back are supplied by dorsal branches of spinal nerves

1

Auscultation triangle on the back is located medial to the scapula

Serratus posterior superior muscle is a muscle of inspriation

1

Muscles of the back are arranged in three groups with distinct functions.

1

Erector spinae muscle is made of three colunms.

1

Intermediate muscles of the back are respiratory muscles.

1

Platysma is innervated by a branch of the facial nerve.

1

The platysma is a superficial muscle that overlaps the sternocleidomastoid

1

Accessory nerve is a branch of cervical plexus

1

Phrenic nerve (C3-C5 (primarily C4)) innervates thoracic diaphragm.

1

Internal carotid artery has two cervical branches.

1

The upper end of the jugular vein dilates into internal jugular fossa

1

Near the termination of the internal jugular vein is a smaller dilation, the inferior bulb.

1

An elderly man presented with severe pain beneath the left eye, radiating into the lower eyelid, lateral side of the nose and upper lip. What nerve was involved?

1

To study the compensatory response of selective suprahyoid muscles in elevating the hyoid bone, an experiment was designed in which the posterior belly of the digastric and stylohyoid muscles were paralysed by drugs. The muscular branches of which of the following nerves must be chemically interrupted to produce paralysis in both muscles?

What structure lies deepest in the parotid gland?

1

A deep laceration of the face in the middle of the parotid gland could affect the

1

Pain elicited from an infected facial wound is primarily conveyed by what nerve?

1

Inability to close the lips relates to the action of which muscle?

1

Which muscle will not be affected when the mandibular division of the trigeminal nerve (V3) is anesthetized?

1

The parotid space contains all EXCEPT:

1

Two nerves usually emerge from between the two heads of the lateral pterygoid muscle: the anterior deep temporal nerve and the:

1

Paralysis of which of the following muscles would impede retraction of the mandible?

1

A cranial fracture through the foramen ovale that compresses the enclosed nerve, will have an effect on all muscles EXCEPT:
