Lab 21, Station 4: The larynx
Lab 21 navigation The larynx is the “voice box”—it is the organ of phonation (sound production). It also serves as a valve to regulate airflow to and from the lungs and as a sphincter to prevent foods and liquids from entering the airway. Skeleton of the Larynx Figure 20. Skeleton of the larynx. The “skeleton” […]
Lab 21, Station 3: The pharynx
Lab 21 navigation The pharynx (“throat”) is the upper end of the alimentary canal. It is shared by the digestive and respiratory systems. See Figure 14 and 15. You will study the pharynx from two perspectives: in a mid-sagittal view on a cross-section and in a posterior view on a prosection. Figure 14. The pharynx. […]
Lab 21, Station 2: Skull bones and paranasal sinuses
Lab 21 navigation The skull is divided into two parts: Neurocranium and Viscerocranium. Neurocranium (“brain case”) = Frontal bone, ethmoid, sphenoid, occipital bone, temporal bones (2), and parietal bones (2) The neurocranium has a roof called the calvaria (“skull cap”). Viscerocranium (“facial skeleton”) = Mandible, maxillae (2), zygomatic bones (2), nasal bones (2), lacrimal bones […]
Lab 21, Station 1: Nose and nasal cavities
Lab 21 navigation The nose has two parts: The external nose is on the face. It functions to direct air (and odors) into the nasal cavities. Identify these parts of the external nose on the face: Apex (“tip”) Root Dorsum (“bridge”) Alae Nares (“nostrils”) Figure 1. Parts of the external nose. The “skeleton” of the […]
Lab 21: Overview of the upper and lower respiratory tracts
Students: Unlike most lab sessions, which are dissection-based, this session is a “prosection lab.” Assemble in 5 groups, each having ~16 members. There are 5 learning stations situated around the labs. Pick a station to start at. Groups will spend about 25 minutes at each station, rotating around the labs until they have visited all […]
