Please label Now do the same for me and list the primary dates of eruption Can you look at this diagram of the TMJ then tell me what you understand about it including the movements in your own words, 7-8 yrs 8-9 years 11-12 yrs 10-11 yrs 10-12 yrs 6-7yrs 12-13 yrs 17-21 yrs 17-21 yrs 11-13yrs 6-7 yrs 11-12yrs 10-12yrs 9-10yrs 7-8 yrs 6-7 yrs
Please label The movement at TMJ results due to hyoid muscles and muslces of mastication. THe upper part allows retraction of mandible and protrusion. The joint connect mandible and skull in front ear and allows teh jaw movements. To allow the smooth motion of condyles to its original position on closing the mouth a soft disk of cartilage is presente between temporal bone and condyle. The disk absorbs the shock to tmj from chewing or the movement which have strong force. Can you answer the following: 1.Describe the function of the gingivae Gingval is a tissue that surrounds and protects the teeth and underlying the bone. It is attached to tooth and form a protective seal that prevent the infection. 2.Describe the function of the supporting tissues This attached the tooth to the jaw bone and support the tooth formation. It also helps to resorption of bone at the time tooth movement, sensation and eruption. 3.Tell me about the position of the salivary gland and muscles of mastication, you can draw a diagram to show me when you explain, There are main three party of salivary gland that are parotid gland, Submandibular gland and sublingual gland. Position of parotid salivary gland is just under the lobes of year. Position of Submandibular gland is under each side of jawbone and position of sublingual gland is presents under the tongue.

Please label (Source:Muscles of Mastication (Chewing),2019) Equation2: Salivary gland (Source:The salivary gland,2019) 4.Tell me about the nerve supply to the teeth and the supporting structures again do not be afraidto use diagrams to show me. The inferior dental nerve which is also known as the inferior alveolar nerve provide supply sensation to lower teeth. The nerve is branch of mandibular nerve which travels behind lateral pterygoid muscle.
