Lab 28: Dissection: Orbit and Ear
Download this lab as a PDF Goals Identify the bony walls and foramina of the orbit. Open the orbit via a superior approach on both sides and dissect its contents. Find the lacrimal gland in the cadaver and study the lacrimal apparatus on a model. Dissect the orbit from an anterior approach on both sides […]

Download this lab as a PDF Goals Identify the bones associated with the face and parotid gland. Identify surface landmarks on the face. Clean and identify muscles of facial expression. Identify branches of the facial nerve on the face. Locate the major sensory nerves of the face. Identify the facial artery and vein. Identify the […]

Lab 26: 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 5: Blood supply and circulation
Arterial blood supply Review from FMS 501 Vertebral arteries Supplying the brainstem and cerebellum Anterior and posterior spinal Posterior inferior cerebellar Basilar (unpaired)—multiple pontine branches also come directly off the basilar artery Anterior inferior cerebellar Superior cerebellar Posterior cerebral posterior communicating Internal carotid Supplying the midbrain, thalamus, hypothalamus, and cerebrum Middle cerebral Anterior communicating Anterior […]
Lab 3: The brainstem
Parts of the brainstem Midbrain Mesencephalon Pons Metencephalon Medulla Myelencephalon See Figure 3.1, Review 3.1, and Review 3.2. The basal subdivision of the brainstem is the most anterior and contains mostly the descending fiber tracts. The tegmentum is the location of the cranial nerve nuclei, ascending fiber tracts, and the reticular formation. In the medulla, […]
Lab 2. Diencephalon
Thalamus See Check Yourself 2.1. The thalamus is key structure that relays information to the cortex associated with motor and sensory information. (These will further be described during the Functional Neuroanatomy lectures.) There are also thalamus nuclei that form the connections in the memory and emotion circuit from the hippocampal formation. This portion of the […]
1. Development of the Nervous System
Neurulation and formation of the Central Nervous System A quick review of neurulation from FMS 501 . . . 1. After migration and patterning, the dorsal layer of ectoderm further differentiates into neuroectoderm. Neuroectoderm begins to invaginate at ~18 days, forming a neural groove between paired neural folds. The neural folds later fuse dorsally, forming […]

3. Functional neuroanatomy and vasculature, part 2
Long ascending and descending pathways The three major longitudinal pathways the corticospinal tract, posterior column-medial lemniscus, and anterolateral system can be followed systematically to and from the cerebral cortex, through brain stem and to and from spinal cord. A key feature of all these pathways is to note the location where their tracts cross to […]
