Lab 22: Scalp, Cranial Cavity, and Meninges
Download this lab as a PDF Goals Identify the layers of the SCALP. Examine the dura mater and the dural septae. Remove the brain and study: meningeal coverings, gross features, and arterial supply (circle of Willis). Examine the internal aspect of the base of the skull and the cranial fossae. Identify cranial nerves and blood […]
Lab 21, Station 5: Lungs, pleura, trachea, and bronchi
Lab 21 navigation External Anatomy of the Lungs Apex and base Lobes Left lung = superior (upper) and inferior (lower) Right lung = superior (upper), middle, and inferior (lower) Surfaces = costal, mediastinal, and diaphragmatic Anterior and inferior borders In left lung: Cardiac notch and lingula Oblique fissure in both lungs; horizontal fissure in right lung […]
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 […]

There is no excerpt because this is a protected post.
Pterygopalatine fossa
Optional reading Moore’s Clinically Oriented Anatomy, 9th ed., Pterygopalatine fossa section through The bottom line: Pterygopalatine fossa. The pterygopalatine fossa (PPF) is a small, bilateral bony space immediately behind the maxilla. Shaped like an inverted teardrop, it is about the size of a thumbnail. Bony borders Anterior: Posterior surface of maxilla. Posterior: Anterior surface of […]
Root of the neck
Optional reading Moore’s Clinically Oriented Anatomy, 9th ed., Deep structures of neck section through Nerves in root of neck. The root of the neck (base of the neck, cervicothoracic region) is important because it is the region of continuity between the neck and thorax, and the neck and upper limbs. It can be somewhat confusing […]
