The Muscular System Views
1 PRE-LAB EXERCISES Before coming to lab, get familiar with a few muscle groups we’ll be exploring during lab. Using Visible Body’s Human Anatomy Atlas, go to the Views section. Under Systems, scroll down to the Muscular System views. Select the view Expression and find the following muscles. When you select a muscle, note the book icon in the content box. Selecting this icon allows you to read the muscle’s definition. 1. Occipitofrontalis (epicranius) 2. Orbicularis oculi 3. Orbicularis oris 4. Nasalis 5. Zygomaticus major Return to Muscular System views, select the view Head Rotation and find the following muscles. 1. Sternocleidomastoid 2. Scalene group (anterior, middle, posterior) 2 IN-LAB EXERCISES Use the following modules to guide your exploration of the head and neck region of the muscular system. As you explore the modules, locate the muscles on any charts, models, or specimen available. Please note that these muscles act on the head and neck – those that are located in the neck but act on the back are in a separate section. When reviewing the action of a muscle, it will be helpful to think about where the muscle is located and where the insertion is. Muscle physiology requires that a muscle will “pull” instead of “push” during contraction, and the insertion is the part that will move. Imagine that the muscle is “pulling” on the bone or tissue it is attached to at the insertion. Access 3D views and animated muscle actions in Visible Body’s Human Anatomy Atlas, which will be especially helpful to visualize muscle actions. -

Rodella Section of Anatomy and Physiopathology, Department of Clinical and Experimental Sciences, University of Brescia, Brescia, Italy [Received: 1 June 2016; Accepted: 18 July 2016] Background: Additional extrinsic muscles of the tongue are reported in literature and one of them is the myloglossus muscle (MGM). Since MGM is nowadays considered as anatomical variant, the aim of this study is to clarify some open questions by evaluating and describing the myloglossal anatomy (including both MGM and its ligamentous counterpart) during human cadaver dissections. Materials and methods: Twenty-one regions (including masticator space, sublin- gual space and adjacent areas) were dissected and the presence and appearance of myloglossus were considered, together with its proximal and distal insertions, vascularisation and innervation. Results: The myloglossus was present in 61.9% of cases with muscular, ligamen- tous or mixed appearance and either bony or muscular insertion. Facial artery pro- vided myloglossal vascularisation in the 84.62% and lingual artery in the 15.38%; innervation was granted by the trigeminal system (buccal nerve and mylohyoid nerve), sometimes (46.15%) with hypoglossal component. Conclusions: These data suggest us to not consider myloglossus as a rare ana- tomical variant. -

Chin Ptosis: Classification, Anatomy, and Correction/Garfein, Zide 3
Chin Ptosis: Classification, Anatomy, and Correction Evan S. Garfein, M.D.,1 and Barry M. Zide, D.M.D., M.D.1 ABSTRACT For years, the notion of chin ptosis was somehow integrated with the concept of witch’s chin. That was a mistake on many levels because chin droop has four major causes, all different and with some overlap. With this article, the surgeon can quickly diagnose which type and which therapeutic modality would work best. In some cases the problem is a simple fix, in others the droop can only be stabilized, and in the final two, definite corrective procedures are available. Of note, in certain situations two types of chin ptosis may overlap because both the patient and the surgeon may each contribute to the problems. For example, in dynamic ptosis, a droop that occurs with smile in the unoperated patient can be exacerbated and further produced by certain surgical methods also. This paper classifies the variations of the problems and explains the anatomy with the final emphasis on long-term surgical correction, well described herein. This article is the ninth on this subject and a review of them all would be helpful (greatly) for understanding the enigmas of the lower face. KEYWORDS: Lip incompetence, chin ptosis, witch’s chin, chin droop, mentalis muscle All chin ptosis patients are not alike. The abnormal anatomy, diagnosis, and management of the proper diagnosis of the type of chin ptosis places the four types of chin ptosis, as well as how to manage patient into one of four categories, which will deter- dynamic ptosis in the presence of other problems— mine who can and who cannot be helped and by which surgeon-caused or not.
