Opening part two
The document outlines representations, codes and conventions, and audience attraction in the opening title sequence of "Mr Teddy". It represents the main character Sam as powerful through props like a gun and martini glass. It also shows some female representations but avoids overly sexualizing them. The sequence uses enigmatic codes over a simple narrative structure. It surveyed audiences on font choices and colors to ensure appeal and recognition for marketing the film.
Case Study 2
1) The document describes a case study of Client 8, a 78-year-old African American male with dementia who was involuntarily hospitalized after his home burned down and his wife perished in the fire.
2) Upon initial hospitalization, Client 8 was observed to be pleasant yet presented symptoms of dementia like impaired memory. A year and a half later, he continues to show dementia symptoms but is otherwise cooperative with his treatment plan.
3) Three main factors are preventing Client 8's discharge: allegations of arson, his ability to do daily activities, and the hospital treating him as mentally ill rather than for dementia. The document proposes alternative treatment plans to discharge Client 8 to a religious home and provide grief counseling.
Neck muscles and triangles
The neck is the region between the head and trunk that contains important structures. It functions to transport the esophagus, trachea, blood vessels, and nerves between the head and chest. The boundaries of the neck include the mandible superiorly, the clavicles inferiorly, and vertebrae posteriorly. The surface anatomy includes palpable structures like the thyroid cartilage. The neck is divided into the anterior and posterior triangles by the sternocleidomastoid muscle. The anterior triangle contains structures like the carotid artery and jugular vein.
The cervical plexus
The cervical plexus is formed from the anterior rami of cervical nerves C1-C4. It has cutaneous branches that innervate the skin of the head and neck, and muscular/communicating branches. The phrenic nerve from C3-C5 is the sole motor nerve to the diaphragm. The cervical plexus and its branches, including the phrenic nerve, are important for sensory innervation and motor control of the neck, diaphragm and related structures.

The document describes the arteries and veins of the head and neck region, including the branches of the external carotid artery like the lingual artery and maxillary artery, as well as the drainage veins like the external jugular vein and internal jugular vein. It provides details on the origin, course, and branches of arteries supplying different structures of the head and neck, such as the common carotid artery, internal carotid artery, and subclavian artery. Key veins that drain blood from the head and neck include the pterygoid plexus, retromandibular vein, and external jugular vein.
Oral mucosa carmi
This document discusses the anatomy and histology of the oral mucosa. It describes the different types of oral mucosa including the lining, masticatory, and specialized mucosa. The major components and layers of the oral epithelium and lamina propria are outlined. Specific structures of the oral mucosa like the gingiva, lips, tongue, and palate are then examined in more detail.
Lymphatics of the head and neck
The lymphatic system helps maintain fluid balance, absorb fats, and defend against microorganisms. The head and neck lymph nodes form a regional collar from below the chin to the back of the head, and a deep vertical group in the neck within the carotid sheath. These nodes drain specific areas of the head and neck and feed into deeper cervical nodes along the internal jugular vein, which ultimately drain into the thoracic duct or right lymphatic duct.

LYMPHATICS HEAD AND NECK
The lymphatic system consists of lymph, lymphatic vessels, lymph nodes, the spleen, thymus, and bone marrow. It develops from lymph sacs that arise from veins. The main functions are restoration of interstitial fluid, absorption and transport of fats, and defense against pathogens. Lymph contains nutrients, waste, and immune cells. It is transported through a network of vessels and ducts and emptied into subclavian veins. Lymph nodes filter lymph and activate immune cells to fight infection. The spleen, thymus, and bone marrow also participate in immune responses.
Lymphatics of the head & neck
Radical neck dissection is a surgical procedure performed to remove lymph nodes and other tissues in the neck during cancer treatment. It is more extensive than a standard or modified neck dissection. The goal is to remove all lymph nodes on one side of the neck below the jawbone to reduce the risk of cancer recurrence or spread. It is performed for advanced primary head and neck cancers or cancers that have already spread to lymph nodes.
General pathology lecture 4 cellular adaptation
Cellular adaptations can occur through hyperplasia, hypertrophy, atrophy, or metaplasia in response to stress or changes in workload or stimulation. Hyperplasia involves an increased number of cells through cell proliferation. Hypertrophy involves cellular enlargement without an increase in cell number. Atrophy is a decrease in cell size. Metaplasia is the replacement of one adult cell type with another. Examples provided include uterine hyperplasia during pregnancy, cardiac hypertrophy in hypertension, muscle fiber atrophy after injury or disuse, and squamous metaplasia in the lungs of smokers. Dysplasia refers to alterations in cell size, shape, and organization and is a pre-cancerous condition.
Lymph and lymphatic system
The document provides an overview of the lymphatic system, including its history, development, components, and functions.

The document discusses various aspects of inflammation and repair. It describes the signs of acute inflammation as redness, heat, swelling, pain, and loss of function. It then covers the events in acute inflammation, including neurologic events like vasoconstriction and vasodilation, hemodynamic events such as increased permeability and slowing of blood flow, and cellular events like margination and emigration of leukocytes. Chronic inflammation and types of inflammation based on location and exudates are also summarized. The document concludes by discussing repair through granulation tissue formation, remodeling and fibrosis.
The cervical plexus
The cervical plexus is formed from the anterior rami of cervical nerves C1-C4. It has cutaneous branches that innervate the skin of the head and neck, and muscular/communicating branches. The phrenic nerve from C3-C5 innervates the diaphragm. The document outlines the branches of the cervical plexus in detail, including the lesser occipital nerve, great auricular nerve, and supraclavicular nerves. It describes the muscular and communicating branches that innervate neck muscles and connect with other nerves.
Trigeminal n.
The trigeminal nerve arises from the pons and has three main divisions - the ophthalmic, maxillary, and mandibular nerves. The ophthalmic nerve is sensory to the eye and parts of the nose and forehead. The maxillary nerve is sensory to parts of the face and upper teeth. The mandibular nerve is mixed sensory and motor, innervating the lower face, teeth, and muscles of mastication. It exits through the foramen ovale. The document then describes the branches and distributions of each trigeminal nerve division.
The oral cavity
The oral cavity is divided into the oral vestibule anteriorly and the oral cavity proper posteriorly by the arch formed by the teeth and gums. The document describes the boundaries and features of these regions as well as the tongue, palate, lips, cheeks, floor of the mouth, and salivary glands. It provides detailed information on the anatomy, muscles, blood supply, and innervation of structures within the oral cavity.
Ears
The ear has three main sections - the outer, middle, and inner ear. The outer ear collects and directs sound waves through the external auditory meatus to the eardrum. The middle ear contains the auditory ossicles that transmit vibrations through to the inner ear. The inner ear senses both hearing and equilibrium, containing the cochlea which detects sounds and the vestibular system that monitors movement and orientation. Receptors in the cochlea and vestibular system of the inner ear enable the senses of hearing and balance.
Eye
The eyeball is located in the orbit and is composed of three layers - the fibrous coat, vascular coat, and neural coat. The fibrous coat includes the sclera and cornea. The vascular coat includes the choroid, ciliary body, and iris. The neural coat is the retina. The eye also contains two cavities filled with fluids - the anterior cavity contains the aqueous humor and posterior cavity contains the vitreous humor. Conditions that can affect vision include myopia, hyperopia, presbyopia, astigmatism, and cataracts. Accessory structures of the eye include the eyelids, lacrimal apparatus, and extraocular muscles.
Face mfe
The document summarizes the anatomy of the face and scalp. It describes the boundaries and regions of the face, as well as the features of specific structures like the lips, cheeks, external ear, eyelids, and nose. It also details the layers of the scalp and various craniofacial muscles including those of the scalp, around the orbit, nose, lips and mouth. For each muscle, the origin, insertion, action, and innervation are provided.
Norma basalis interna
The document describes the anatomy of the anterior, middle, and posterior cranial fossae. It details the boundaries, special features, and foramina of each fossa. Key structures mentioned include the cribriform plate, sella turcica, foramen magnum, optic foramina, and jugular foramen. Clinical significance is noted for fractures involving the cribriform plate which can lead to CSF rhinorrhea and risk of meningitis.
Norma basalis externa
The norma basalis externa involves 11 bones that form the base of the skull. These bones include the palatine process of the maxilla, palatine bone, vomer, medial and lateral pterygoid plates, greater wing of sphenoid, temporal bone, basilar part and lateral part of the occipital bone, and squamous part of the occipital bone. There are several important foramina present, including the incisive canals, greater and lesser palatine foramina, stylomastoid foramen, carotid canal, condyloid foramen, and others that transmit nerves and blood vessels.
Formation of the palate
The palate develops from several processes between the 6th and 8th weeks of development. Initially, the primary palate forms the floor of the nasal pits from the merging of the median nasal processes. Later, the secondary palate forms through the fusion of the bilateral maxillary processes and medial nasal process. The lateral palatine processes grow medially from the maxillary tissues and fuse together along with the nasal septum to form the hard and soft palates. Clefts of the palate can result from non-fusion of the palatine processes and nasal septum.
Development of the tongue
The tongue develops from tissues originating in the pharyngeal arches and swellings in the floor of the mouth. It begins developing at 4 weeks as a tuberculum impar surrounded by two lateral lingual swellings that merge to form the anterior two-thirds of the tongue. The root develops from the hypobranchial eminence originating in the third arch. Muscles of the tongue originate from occipital somites and are innervated by the hypoglossal nerve. The anterior two-thirds receive innervation from the trigeminal nerve and the posterior third from the glossopharyngeal nerve. The tongue separates from the floor of the mouth and develops four types of lingual papillae
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.
Genetic code
This document discusses nucleic acids, RNA, transcription, the genetic code, and protein synthesis. It covers the main types of RNA - mRNA, tRNA, and rRNA. It explains how DNA is transcribed into mRNA, which then moves to ribosomes where tRNA brings amino acids to add to the growing protein chain according to the mRNA codons. The stages of initiation, elongation and termination in protein synthesis are outlined. Mutations that alter DNA and the genetic code can result in genetic diseases.
Nucleic acids
The document discusses the structures and components of nucleic acids DNA and RNA. It explains that nucleic acids are made up of nucleotides, which contain a sugar, phosphate, and one of four nitrogenous bases. The sugars in DNA are deoxyribose and in RNA are ribose. The four bases are adenine, guanine, cytosine, and either thymine in DNA or uracil in RNA. Nucleotides are linked by phosphodiester bonds to form long chains. DNA has a double helix structure with the bases on one strand pairing with their complement on the other strand through hydrogen bonds between A-T and G-C base pairs. DNA replication involves the unwinding of the DNA double helix, and
Metabolic pathways and energy production
Metabolic pathways and energy production involve catabolic reactions that break down molecules and provide energy in the form of ATP. Glycolysis is the process by which glucose is converted to pyruvate through a series of reactions, generating a small amount of ATP. In aerobic conditions, pyruvate undergoes further reactions to form acetyl-CoA and enters the citric acid cycle, while in anaerobic conditions it is reduced to lactate. Coenzymes such as NAD+ and FAD help transfer hydrogen atoms between reactions and link metabolic pathways.
