Digestive System (Pharynx (soft palate + epiglottis (nasopharynx,…

- - - - 3) epiglottis closes to prevent food into larynx
      - 4) peristalsis
      - 2) pharyngeal muscles contract and force the bolus towards oesophagus
      - 5) food through pharynx, the epiglottis opens to start resps
      - 1) food into bolus ny tongue and cheeks
- - - - dog: D: (I3/3, C1/1, PM3/3) x2 = 28teeth P: (I3/3, C1/1, PM4/4, M2/3) x 2= 42teeth
      - cat: D: (I3/3, C1/1, PM3/2) x2 = 26 teeth P: (I3/3, C1/1, PM3/2, M1/1) x 2= 30 teeth
  - - - articulate with temporal bones
        
        temporomandibular joints
      - mandibular symphysis
    - - muscles for mastication
    - - split in lip: philtrum
    - - gingiva
      - hard palate
      - soft palate
        
        oropharynx
        
        nasopharynx
  - - - Sublingual: under tongue
      - Mandibular: angle of jaw, can be mistaken as lymph nodes
      - Zygomatic: eye orbit
      - Parotid: base of ear - (amylase in omnivores and herbivores)
    - - lubricate - mastication and swallowing
      - Thermoregulation - evaporate
- - - - mediastinum: dosal to heart base and between lungs
        
        enters abdomen through oesophageal hiatus
        
        takes 15-30 seconds on average
  - - - peristaltic waves
- - - - inner sac = lesser curvature
        
        lesser omentum
      - food enters via cardiac sphincter
      - outer curve = greater curvature
        
        greater omentum
        
        spleen found here
      - covered in mesentery/ visceral peritoneum
