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. -

The establishment of the tracheoesophageal puncture marked a turning point in the development of successful and dependable voice rehabilitation. Surgical options include both primary and secondary placement of a tracheoesophageal puncture. Though complications, such as pharyngoesophageal spasm or prosthesis leakage may occur, patients should expect functional voice restoration after laryngectomy.

Rajashekhar, Ph.D. Abstract Vowel duration, one of the important acoustic characteristics, is important in vowel perception. Vowel duration varies based on individual, linguistic and non-linguistic characteristics. This study was to study vowel duration in all Telugu vowels across different gender, region and age groups. Using cross sectional study design, a total of 4320 tokens from 72 randomly selected Telugu speaking participants from three age groups, two gender and three region groups were analyzed. Vowel duration of the target vowel was extracted and analyzed using spectrogram. From the results it is interpreted that significant variations in vowel duration of vowels in Telugu exist between children, adolescents and adults; Coastal, Rayalaseema and Telengana speakers. Vowels /e/ and /a:/ had longest vowel duration, while short and long vowels /i/ have shortest vowel duration. Children found to have longer vowel duration as compared to adolescents or adults. Regional influences are seen on vowel duration. Rayalaseema speakers Language in India www.languageinindia.com 13 : 1 February 2013 Krishna Y, Ph.D. -
The Myloglossus in a Human Cadaver Study: Common Or Uncommon Anatomical Structure? B

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. -

Initial Stage of Fetal Development of the Pharyngotympanic Tube Cartilage with Special Reference to Muscle Attachments to the Tube

We examined semiserial histological sections of 20 human fetuses at 14-18 weeks of gestation. As controls, we also observed sections of 5 large fetuses at around 30 weeks. At and around 14 weeks, the tubal cartilage first appeared in the posterior side of the pharyngeal opening of the PTT. The levator veli palatini muscle used a mucosal fold containing the initial cartilage for its downward path to the palate. Moreover, the cartilage is a limited hard attachment for the muscle. Therefore, the PTT and its cartilage seemed to play a critical role in early development of levator veli muscle. In contrast, the cartilage developed so that it extended laterally, along a fascia-like structure that connected with the tensor tympani muscle. This muscle appeared to exert mechanical stress on the initial cartilage. -
