The integumentary system special class lec
The integumentary system consists of the skin, hair, nails, and skin glands. The skin is composed of two principal layers - the epidermis and dermis. The epidermis is made up of stratified squamous epithelium and provides a protective barrier. The dermis lies below the epidermis and contains collagen, elastic fibers, and vasculature that provide strength and nourishment to the skin. Skin appendages include hair follicles, sebaceous glands, sweat glands, and nails. The skin regulates body temperature, protects the body, and plays a role in sensation and immune function.
dermatology.Skin anatomy.(dr.darseem)
The skin has two main layers - the epidermis and dermis. The epidermis is made of stratified squamous epithelium consisting of keratinocytes. The dermis lies below the epidermis and contains collagen, elastic fibers, and ground substance to provide strength and flexibility. It also contains structures like hair follicles, sweat glands, and blood vessels that interface with the environment.
Skin structure and development
The skin has two basic layers - the epidermis and dermis. The epidermis is made up of stratified squamous epithelium and contains melanocytes, Merkel cells, and Langerhans cells. It has five layers - stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. The dermis lies below the epidermis and contains collagen, elastic fibers, and cutaneous structures. It has two layers - a thin papillary dermis and a thick reticular dermis. The skin develops from the ectoderm and mesoderm germ layers during embryogenesis.
Skin
The skin has three main layers - the epidermis, dermis and subcutaneous layer. The epidermis has five layers and does not have its own blood supply. The dermis lies below and has two layers, the papillary and reticular layers. It contains collagen, elastin and fibroblasts. Below this is the subcutaneous layer made of fat. The skin has seven main functions - sensation, heat regulation, absorption, protection, excretion, secretion and vitamin D production.
Skin anatomy
The skin is the largest organ of the body, weighing approximately 4 kg for an adult and covering an area of about 2 square meters. It has several important functions, including providing protection, regulating temperature, and serving as a sensory organ.
The skin is composed of three main layers - the epidermis, dermis, and hypodermis. The epidermis is made up of stratified squamous epithelium with the basal, prickle, and granular cell layers. Below this is the dermis containing collagen, elastic fibers, and appendages. The deepest layer is the hypodermis, which stores fat.
The skin contains several cell types including keratinocytes, melanocytes, Langerh
Apocrine and eccrine glands
Eccrine and apocrine sweat glands and sebaceous glands are described. Eccrine glands are present all over the body and secrete sweat to regulate temperature through sympathetic innervation. Apocrine glands are located in axillae and genital regions and secrete an oily fluid during puberty under androgen stimulation. Sebaceous glands are always associated with hair follicles and their sebum production helps moisturize skin and hair.
Dermis
The dermis is the middle layer of skin located between the epidermis and subcutaneous fat. It varies in thickness from 1mm on eyelids to 5mm on the back and makes up 15-20% of body weight. The dermis provides nutrients to the epidermis and dermal appendages, cushions the body against injury, retains water, aids thermal regulation, and contains receptors for sensory stimuli. It has two layers - a thin papillary dermis that interdigitates with the epidermis, and a thick reticular dermis that merges with subcutaneous fat and contains large collagen and elastic fibers. The dermis develops from mesenchymal cells and contains components like elastin, collagen, ground
Anatomy of Nail And Applied Aspects
The document discusses the anatomy and applied aspects of nails. It describes the components of nails including the nail matrix, nail bed, cuticle, nail plate, and nail folds. It covers the development, structure, composition, blood supply, nerve supply, growth and functions of nails. The document also discusses various nail disorders and conditions, nail signs in systemic diseases, and the importance of nail analysis in forensic medicine and general medicine.

Anatomy and physiology of sweat glands
This presentation includes structure and functions of sweat glands i.e. eccrine, apocrine and apoeccrine glands. mechanism of sweat secretion and role of sweat in thermoregulation is included.
Surgical flaps
Skin has three layers - the epidermis, dermis and hypodermis. The dermis contains blood vessels, sweat glands and hair follicles. There are two networks of blood vessels in the skin. Skin flaps use a block of vascularized tissue from a donor site to reconstruct another area. Flaps can be classified based on their blood supply as random pattern or axial pattern flaps, and based on their location as local or distant flaps. Local flaps include rotational, transposition and advancement flaps. Distant flaps include myocutaneous and fasciocutaneous flaps and are used when local tissue is inadequate. Free flaps completely disconnect the blood supply for transfer to another site.
Anatomy of hair and hair cycle
Hair follicles grow at an angle with the major part developing from epithelial cells. The upper follicle is permanent while the lower regenerates with each hair cycle. Hair follicles contain the hair bulb with dermal papilla, hair matrix cells, inner and outer root sheaths, and the hair shaft. The hair cycle consists of growth (anagen), involution (catagen), and resting (telogen) phases over 3-7 years. During anagen, hair grows rapidly from matrix cells. Catagen is a short transition phase and telogen is a resting phase before the next anagen.
Suture materials
Sutures can be classified into absorbable and non-absorbable types based on how the body breaks them down. Absorbable sutures such as polyglycolic acid and polyglactin 910 degrade over time as the wound heals, while non-absorbable sutures like polypropylene, nylon, polyester and stainless steel resist breakdown and typically need to be removed. Sutures can also be monofilament or multifilament, and coated or uncoated, with these properties affecting factors like tensile strength, tissue reaction and knot security. Common sutures discussed include catgut, polypropylene, nylon, polyester, silk and steel.
Acne scar treatment
Acne scarring can be classified as icepick, boxcar, or rolling scars based on their width, depth, and architecture. Treatment options include topical agents, superficial and medium-depth peels, dermabrasion, fillers, fat transfer, needling, fractional photothermolysis, and surgical techniques like excision, grafting, and subcision. Superficial peels improve boxcar scars but may require multiple sessions. Dermabrasion is effective for acne scars but requires proper patient selection and technique. Fillers and fat transfer work best for atrophic depressed scars. Needling induces collagen without damage to induce healing. Surgical techniques are best for deep

Neck lift, forehead and thread lift
This document discusses various surgical approaches for forehead and brow lifting as well as neck lifting. For forehead lifts, it describes techniques like the coronal approach and its disadvantages like scalp numbness. It also covers other approaches like the temple approach and endoscopic approach. For neck lifts, it discusses factors to consider like skin elasticity and platysma muscle treatment. It provides details on the surgical process for different grades of neck laxity and describes techniques like subcutaneous lipectomy and platysma plication. Post-operative care is also outlined for both forehead and neck procedures.
Wound healing
Wound healing is a complex, dynamic process involving several phases: inflammatory, proliferative, and remodeling. The inflammatory phase involves hemostasis and inflammation to limit blood loss and seal the wound. The proliferative phase fills the wound gap with granulation tissue through fibroplasia, angiogenesis, and re-epithelialization. The remodeling phase involves regression of vessels and granulation tissue, wound contraction, and collagen remodeling to strengthen the scar. Successful wound healing depends on factors like adequate blood supply, infection control, and avoiding risks such as smoking, which can impair healing.
Introduction to laser dermatology 1
This document discusses laser therapy and principles of laser use. It provides background on the history of lasers including early science fiction references. It describes the basic science of how lasers work through stimulated emission and outlines the key components of lasers. The document discusses principles of selective photothermolysis and factors that influence laser effectiveness such as wavelength, pulse duration, and energy density. It also reviews laser safety and how lasers are used in a clinical setting.
Sweat gland - anatomy and function
Eccrine sweat glands are the main sweat glands in humans. They produce a hypotonic sweat through active transport of ions from interstitial fluid into the secretory coil, and partial reabsorption of sodium and chloride in the ducts. Sweating is controlled by the sympathetic nervous system and helps regulate body temperature by evaporative cooling. The three main stimuli for sweating are thermal, emotional, and gustatory. Sweat contains water and low concentrations of ions similar to plasma but is hypotonic due to reabsorption in ducts.
Anatomy of skin
The document summarizes the anatomy and physiology of the skin. It describes the three layers of skin - epidermis, dermis and subcutaneous tissue. It explains the structure and functions of the epidermis and dermis. The key functions of skin include protection, temperature regulation through sweating and blood flow, and sensory perception. The skin regulates body temperature through mechanisms like sweating, shivering and blood flow to dissipate or conserve heat.
Pathology of Skin - Introduction
This document provides an overview of a dermatopathology course, including learning objectives, session details, sample exam questions, and study tips. It discusses key histopathological terms, classifications of skin diseases, common and rare skin conditions, and outlines the curriculum to be covered, including acute and chronic inflammatory diseases, infections, blistering diseases, and neoplastic conditions.
The skin (integumentary system)
The power point is just to help learners to have basic understanding on the anatomy and physiology of the skin (integumentary system).
The two major classes of the skin has been briefly stated as well as the major layers of the skin.
Hair follicle
The hair follicle contains several key structures that work together to produce hair. The papilla at the base is made of connective tissue and contains a blood vessel loop. Surrounding the papilla is the matrix, containing epithelial cells and melanocytes. The matrix is one of the fastest growing cell populations and produces the cells that form the hair fiber and inner root sheath. The root sheath surrounds the hair fiber and is composed of three layers. Other structures associated with hair follicles include arrector pili muscles that cause hairs to stand up, sebaceous glands that secrete oil, and sweat glands of two main types.
Facial nerve anatomy, pathology
The document discusses the anatomy, examination, diagnosis, and treatment of facial nerve palsy. It describes the motor, parasympathetic, and sensory parts of the facial nerve and their origins and functions. Examination of the frontal branch and tests for synkinesis, lacrimation, gustation, and sialometry can localize lesions. Bell's palsy is an acute idiopathic peripheral palsy without other cranial nerve involvement. Treatment may include corticosteroids, antivirals, corneal protection, decompression, and physiotherapy. Complications can include incomplete recovery or synkinesis.
Role of Triamcinolone in Hypertrophic scar and keloid
Triamcinolone is a corticosteroid commonly used to treat keloids and hypertrophic scars. It works by suppressing inflammation and inhibiting collagen formation. It can be administered alone or in combination with other treatments like 5-FU, verapamil, bleomycin, laser therapy, pressure therapy, and silicone gel sheets. Combination treatments are generally more effective with fewer side effects. Triamcinolone reduces scar size and recurrence rates when used alone or after scar excision. However, side effects like skin atrophy and pigmentation changes can occur.
Wound healing
The document discusses the stages of wound healing including hemostasis, inflammation, proliferation, and remodeling, and the factors that influence wound healing such as wound type, patient health, and environmental conditions. It also covers abnormal wound healing which can result in hypertrophic or keloid scarring, and treatments for scarring including pressure therapy, steroid injections, and surgery.

The skin is the body's largest organ, making up 16% of total body weight with a surface area of 1.2 to 2.3 square meters. It has two main layers - the epidermis and dermis. The epidermis is the thin outer layer made of five distinct cell layers that undergoes a process of keratinization to form a protective barrier. The dermis lies below the epidermis and is 20 to 40 times thicker, providing structure and housing blood vessels, nerves, and glands. The skin serves several important functions like protection, temperature regulation, sensation, and vitamin D synthesis.

The document discusses the functions and structure of human skin. Skin has several key functions: protection, sensation, temperature regulation, excretion. It protects against microorganisms, ultraviolet light, dehydration and abrasions. Skin detects sensations like hot, cold, touch, pressure and pain. It helps regulate temperature through control of blood flow and sweat gland activity. Skin also helps with excretion of waste and gland secretions. Structurally, skin has three layers - epidermis, dermis and hypodermis. The epidermis is composed of multiple strata and provides protection. The dermis is made of connective tissue. Skin color is determined by pigments, blood circulation and thickness of the outer layer.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
