Jarvis Chapter 13 Head, face, Neck and Lymphs Flashcards
Rigid bony box that protects the brain and special sense organs it includes the bones of the cranium and the face.
Skull
Cranial Bones
- Frontal
- Parietal
- Occipital
- Temporal
Immovable joints where adjacent and cranial bones unite
Suture
Crowns the head from ear to ear at the union of the frontal and parietal bones
Coronal sutures
Separates the head lengthwise between the two parietal bones
Sagittal Sutures
Separates the paretal bones crosswise from the occipital bone
Lamboid Sutures
Palpable spinous process of C7
Vertebra prominens
Opening between eyelids- are equally bilateral.
Palpebral fissures
The creases extending from the nose to each corner of the mouth, should look symmetrical.
Nasolabial folds
Facial nerve. mediates the facial muscles.
Cranial nerve VII
Trigeminal nerve. mediates the facial sensations of pain or touch
Cranial nerve V
Cranial Nerve V
Trigeminal
Cranial nerve VII
Facial
Salivary glands in the cheeks over the mandible, anterior to and below the ear. largest of the salivary glands but are not normally palpable. enlarged with mumps and AIDS
Parotid glands
Salivary glands beneath the mandible at the angle of the jaw
Submandibular glands
Salivary glands. in the floor of the mouth
Sublingual glands
Lies superior to the temporalis muscle. its pulsation is palpable anterior to the ear
Temporal artery
Branches off common carotid and runs inward and upward to supply the brain
Internal carotid
Supplies the face, salivary glands, and superficial temporal area
External Carotid
Innervatd by cranial nerve XI. arises from the sternum and clavicle and extends diagonally across the neck to the mastid process behind the ear. accomplishes head rotation and head flexion
Sternomastoid muscle
Move shoulders and extend and turn the head
Trapezius
AKA upper trachial ring. just above the thyroid isthmus
Cricoid cartilage
Above cricoid cartilage. Adam’s apple
Thyroid cartilage
Above thyroid cartilage. At level of the floor of the mouth
Hyoid bone
