Submental: midline, behind the tip of the mandible (tongue, floor of mouth, lips) Superficial Cervical: overlying the sternomastoid muscle (skin of neck and ear) Posterior Cervical: in the posterior triangle along the edge of the trapezius muscle (posterior scalp, thyroid) Supraclavicular: just above and behind the clavicle, at the sternomastoid muscle (upper abdomonial, lungs, breast, arm) When nodes are abnormal, explore the area proximal (upstream) to the location of the abnormal node. It is usually most efficient to palpate with both hands, comparing the two sides symmetrically. However, the submental gland under the tip of the chin is easier to explore with one hand. When you palpate with one hand, use your other hand to position the person's head. Mouth Oral Cavity: Short passage bordered by the lips, palate, cheeks and tongue o Lips: anterior border of the oral cavity o Hard palate: anterior; made up of bone and is whitish in color. o Soft palate: posterior; arch of muscle that is pinker in color and mobile o Cheeks: o Tongue: a mass of striated muscle arranged in a crosswise pattern so that it can change shape and position. The frenulum is a midline fold of tissue that connects the tongue to the floor of the mouth. Involved in mastication, swallowing, cleansing the teeth, formation of speech, and taste sensation. Uvula: free projection hanging down from the middle of the soft palate
