The muscles of the head and neck allow for. It is controlled by cranial nerves 5 and seven. The head and the neck have a rich supply in lymph nodes. Occipital: at the base of the skull. Submental: midline, behind the tip of the mandible. Submandibular: halfway between the angle and the tip of the mandible. Tonsillar: under the angle of the mandible. Deep cervical: in the posterior triangle along the edge of the trapezius. Supraclavicular: just above and behind the clavicle, at the sternomastoid muscle. The bones of neonatal skull are separated by sutures and by fontanelles. The fontanelles allow for the brain to grow during the first year. They gradually ossify; the triangle shaped posterior fontanelle is closed by 1 to 2 months, the diamond shaped anterior fontanelle closes between 9 months to 2 years. The lymphoid tissue develops to adult size at age 6 but continues to grow till 10 -11 years old.
