It lists the specific bones that will be examined, including the cranial bones (occipital, frontal, sphenoid, ethmoid, temporal), facial bones (mandible, zygomatic, maxilla, palatine, vomer, nasal), and associated bones (hyoid, malleus, incus, stapes). It also notes that the first quiz for the class will be next week.

Scalp
The scalp consists of 5 layers - skin, connective tissue, aponeurosis, loose areolar tissue, and pericranium. The skin is thick and contains numerous hair follicles, sebaceous glands, and sweat glands. The connective tissue below is dense and fibrous, containing a rich blood supply where vessels are adherent. Below this is the aponeurosis layer, containing two muscle bellies connected by the epicranial aponeurosis. The loose areolar tissue below forms a potential space containing emissary veins that can allow spread of infection to intracranial sinuses. The outermost pericranium layer is loosely attached to skull bones and firmly
Occipitalis
The document discusses the skeletal structure of the head and neck, including the bones and features of the occipital bone such as the external occipital protuberance and crests. It also labels diagrams of the occipital bone, identifying the sagittal and lambdoid sutures, parietal bone, occipital bone, and nuchal lines on the back of the skull. The document appears to be educational material about human anatomy for dental students.
The digastric triangle
The posterior belly of the digastric muscle originates from the mastoid notch of the temporal bone and inserts on the intermediate tendon which connects to the hyoid bone. It has relationships superiorly with the external carotid artery branches and inferiorly with the internal carotid artery, internal jugular vein and cranial nerves IX, X, XI, XII. The posterior belly is supplied by the posterior auricular and occipital arteries and innervated by the facial nerve.
The hyoglossal muscle
The hyoglossus muscle originates from the body and greater horn of the hyoid bone and inserts into the inferior aspects of the lateral part of the tongue. It functions to depress the tongue, especially pulling its sides inferiorly, and helps shorten or retrude the tongue. The hyoglossus is innervated by the hypoglossal nerve and supplied by branches of the lingual and facial arteries.
16 parotid bed
The parotid bed is an irregular space located in the face that houses the parotid gland. Several nerves and blood vessels pass through the substance of the parotid gland as it is molded into the parotid bed, including the facial nerve, trigeminal nerve, external carotid artery, and tributaries of the external jugular vein. The parotid gland is the largest of the three major salivary glands and is enclosed in a capsule within the parotid bed. It has an irregular shape and lobes that extend into adjacent spaces.
Norma Basalis
The document summarizes key parts and features of the human skull and neck skeleton as seen from different angles or "norma" views. It describes bones and structures in the anterior (front) part of the skull such as the palatine processes, fossae, and crests. The middle part contains the vomer bone and pterygoid processes. The posterior (back) part outlines structures like the mastoid process, mandibular fossa, and various foramina for cranial nerves and blood vessels. The summary focuses on providing an overview of the main bones and landmarks covered in the anatomical diagram.
Introduction to osteology
Osteology, derived from the from Greek ὀστέον (ostéon) 'bones', and λόγος (logos) 'study', is the scientific study of bones, practised by osteologists. A subdiscipline of anatomy, anthropology, and paleontology, osteology is the detailed study of the structure of bones, skeletal elements, teeth, microbone morphology, function, disease, pathology, the process of ossification (from cartilaginous molds), and the resistance and hardness of bones (biophysics).[1]
Osteologists frequently work in the public and private sector as consultants for museums, scientists for research laboratories, scientists for medical investigations and/or for companies producing osteological reproductions in an academic context.
Osteology and osteologists should not be confused with osteopathy and its practitioners, osteopaths.
Neck muscles
The document summarizes key neck muscles - the sternocleidomastoid and scalenes. It notes that the neck contains 26 muscles total. The sternocleidomastoid is one of the largest neck muscles, arising from two heads and enabling head and neck movement. The scalenes consist of three muscles - anterior, medius and posterior. Both the sternocleidomastoid and scalenes work together to enable actions like lateral neck flexion and contralateral head rotation.

The body has an upper dorsum surface and lower ventral surface. The dorsum has oral and pharyngeal parts divided by the sulcus terminalis. The oral part contains papillae and sits in the mouth floor. The pharyngeal part lacks papillae and forms the mouth's back wall. Muscles like the genioglossus connect the tongue to other structures and allow movement. Arteries supply blood while veins drain it. Nerves provide sensation and control. The tongue develops from arches in the
Anterior cranial-fossa
The anterior cranial fossa is the highest and most anterior of the three fossae of the internal skull. It is bounded by the frontal bone anteriorly and laterally, the sphenoid bone posteriorly and medially, and the lesser wings of the sphenoid bone posteriorly and laterally. It contains the inferior and anterior parts of the frontal lobes and important structures like the cribriform plate and crista galli. Injuries and tumors in this region can impact smell, vision, eye movement and cause CSF leaks. Both endoscopic and open craniotomy surgical approaches are used to access the anterior cranial fossa.

The four major sutures are the coronal
The four major sutures of the skull are the coronal, sagittal, lambdoid, and squamous sutures. Sutures connect the frontal, parietal, temporal, and occipital bones of the skull and allow movement during birth by acting as expansion joints that enable even growth of the bones and brain. There are also two fontanelles between the skull bones, the anterior and posterior fontanelles, which are soft spots in an infant's skull that close during the first two years of life.
Norma frontalis
The document summarizes the key anatomical regions and structures of the anterior view of the skull (norma frontalis). It describes the 6 regions - frontal, orbital, nasal, zygomatic, maxillary, mandibular. For each region it outlines the boundaries, bones involved, characteristic features and openings. The orbital region is described in most detail, outlining the bones forming its walls and boundaries, as well as openings into the orbital cavity.
Skull
The skull is composed of 22 bones that form the cranium (housing the brain) and face. The 8 bones of the cranium are the frontal, occipital, sphenoid, ethmoid, and two each of the parietal and temporal bones. These bones protect the brain and support structures like the spinal cord. The 14 bones of the face are the mandible, maxillae, zygomatic, lacrimal, nasal, inferior conchae, palatine, and vomer bones, which form structures like the nose and jaws.

This document provides an overview of the anatomy of the scalp, face, and temporal region. It describes the layers of the scalp including the skin, connective tissue, aponeurosis, and pericranium. It details the muscles of the scalp including the occipitofrontalis. It discusses the sensory and vascular supply as well as lymph drainage of the scalp. It then describes the bones, muscles, nerves, vessels, and lymph drainage of the face. Finally, it briefly mentions that the temporal region is located on the side of the head and contains the temporal lobe of the brain.
