The document summarizes the histology of the female reproductive system. It describes the layers of the ovary including the cortex containing ovarian follicles and stroma, and the medulla containing blood vessels, connective tissue, and hilus cells. It also describes the layers of the uterus (perimetrium, myometrium, endometrium), uterine tubes (mucous membrane, muscle coat, serosa), and vagina (mucous membrane with stratified squamous epithelium, muscle coat, adventitia).
There are three main types of muscle tissue: skeletal, cardiac, and smooth muscle. Skeletal muscle is composed of large multinucleated fibers that contract quickly and voluntarily. Cardiac muscle is composed of branched cells connected by intercalated disks that contract involuntarily and rhythmically. Smooth muscle is composed of grouped fusiform cells that contract slowly and involuntarily. Each muscle type has a structure adapted to its function and shows regeneration capacity.
The small intestine extends from the stomach to the large intestine. It is further divided into the duodenum, jejunum, and ileum. The small intestine absorbs nutrients through fingerlike projections called villi lined with absorptive enterocytes. Peristalsis and segmentation contractions mix and propel intestinal contents. The large intestine extends from the ileum to the anus and absorbs water and forms feces for excretion. Diseases include obstruction, malabsorption, and abnormalities in defecation like constipation and diarrhea.

HISTOLOGY: EPITHELIA AND GLANDS CONNECTIVE TISSUE PROPER CARTILAGE AND BONEOHupdates
This document discusses the four basic types of tissues in the body - epithelial tissue, connective tissue, muscular tissue, and nervous tissue. It focuses on epithelia and glands, as well as connective tissue proper. It describes the structure, function, classification and secretory mechanisms of epithelial tissues, including simple and stratified epithelia. It also discusses exocrine and endocrine glands, and the histology of connective tissue proper, including the cells, fibers and ground substance that make up this widespread tissue.
The document discusses the histology of the female reproductive system, specifically the cervix and vagina. It describes the structure of the cervix, including the cervical canal, internal and external openings, and fornix. The endocervical region contains a mucosa with deep folds and highly branched cervical glands, as well as a dense fibrous lamina propria and less compact muscularis than the uterus. The exocervix has a similar mucosa to the vagina. The vagina contains a stratified squamous epithelium lining, dense irregular connective tissue lamina propria with elastic fibers, prominent ridges and papillae but no glands, and inner circular and outer longitudinal layers of smooth muscle.
The integumentary system consists of two main layers - the epidermis and dermis. The epidermis is made of stratified squamous epithelium and contains 5 layers (stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum). The dermis lies below the epidermis and contains collagen, fibers and houses structures like hair follicles, sebaceous glands and sweat glands. Hair follicles extend from the epidermis into the dermis and contain the hair shaft, root and arrector pili muscle. Sebaceous glands and sweat glands also originate in the dermis and connect to
The document describes the key parts of the female reproductive system including internal organs like the ovaries, oviducts, uterus, and vagina as well as external genitalia. It provides details on the ovaries and ovarian follicles, discussing their development from primordial to secondary to graafian follicles. It explains ovulation, the formation and role of the corpus luteum, and the ovarian and hormonal cycles. Key points are summarized around follicular development and atresia, ovulation, the corpus luteum, and the oviduct's role in transporting the ovum and embryo.
The tongue is a muscular organ located in the oral cavity that is attached to the hyoid bone, mandible, styloid process, and pharynx. It has several types of papillae on its dorsal surface that contain taste buds and aid in tasting, manipulating food, and cleaning teeth. The posterior one-third of the tongue differs from the anterior two-thirds in that it lacks filiform and fungiform papillae and contains lymphatic tissue. Cancer of the tongue is diagnosed through histological examination and treated with radiotherapy or surgery.
The lymphatic system consists of lymph vessels, lymph nodes, spleen, thymus, tonsils, and other lymphoid tissues. The lymph vessels return interstitial fluid to the blood circulation and help protect the body from disease. Primary lymphoid organs like the bone marrow and thymus produce immune cells, while secondary organs like lymph nodes, spleen, and mucosa-associated lymphoid tissue house and transport lymphocytes throughout the body. Histologically, lymphoid tissues contain aggregates of lymphocytes and other immune cells organized into structures like follicles, cords, and sheaths that vary between organs.
Cartilage is a resilient and smooth elastic connective tissue, a rubber-like padding that covers and protects the ends of long bones at the joints, and is a structural component of the rib cage, the ear, the nose, the bronchial tubes, the intervertebral discs, and many other body components.
Histology
Junqueira’s Basic Histology Text and Atlas, 15th Ed
1. Gastrulation begins around day 14-15 with the formation of the primitive streak on the dorsal surface of the embryo, through which epiblast cells migrate inward to form the mesoderm and endoderm.
2. Cells invaginating the primitive pit move forward to form the notochordal process, which later forms the definitive notochord, a solid cord of cells.
3. By the end of the 4th week, the primitive streak begins to regress and disappear, and the embryonic disc becomes elongated with broad and narrow ends.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.
Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
