Plastron – *The plastron or ventral shield is composed of nine bony pieces, of which eight are paired. *The anterior pairs of bones are the episternals, the middle pairs are the hyosternals and hyposternals, and the hinder pairs are the xiphisternals. The unpaired piece is called entosternal. *The precise nature of the bones of the plastron is still unknown. *Some consider them as a complete structure corresponding with the sternum or breast-bone; others regard them as wholly integumentary; while

Bone tissue structure Bone is hierarchically organized. Zooming in the bone structure (Fig. 4a), we find the osteons or Haversian systems, which are the basic unit of structure of compact bone. Osteons consist of concentrically arranged layers, or lamellae, of compact bone tissue, that surround a central canal, the Haversian canal, where bone’s blood supplies and nerves can be found (Fig. 4b). Sequential concentric lamellae have alternate fiber orientations with each other, spiralling around the

People have enjoyed jumping rope for centuries. We know that even in ancient civilizations there was this type of activity for people of all ages. There are even hieroglyphics that depict the Egyptians with vines, and there are descriptions of these people using the activity of jumping for fun and self-satisfaction. Children all take enormous delight in the jumping involved in this simple exercise. Adults somehow have usually managed to lose the connection to the fun in jumping, but if you give this

Adipose is a loose connective tissue that makes up the spaces in between our organs and tissues which provides structural and metabolic support. The main role of adipose is to store energy in the form of lipids. However it also serves as cushions and insulates the body. Adipose tissue – more particularly, the brown adipose tissue – was first identified by Swiss naturalist Conrad Gessner in 1551. When Conrad Gessner first discovered the tissue he described it as it was “neither fat, nor flesh – but

OH MY GOD!!!!WHAT A BODY MANNNNN!!!!!!!!!! Body building is an art.It is the use of progressive resistance exercise to control and develop once musculature.Nowadays everyone including women goes to gym to keep their body fit,six packs are not only a style for men but also it has become a part of their personality. An individual who engages in the act of bodybuilding are known as body builder. For body building ,body building training are given,in which the professional trainers trains the people

Barrier membrane: Generally, there are two types of membrane used, resorbable and non resorbable. Non resorbable expanded polytetrafluoroethylene(ePTFE) membrane can be used to maintain the alveolar ridge after extraction. A paper by the Lekovic V et al, looked at the use of a resorbable membrane compared to a control site in 16 patients. A polyglycolide⁄ lactide membrane was placed and assessed after six months. The experimental sites showed significantly

arch are lingual bar and lingual plate. Lingual bar is a half-pear shaped steel rod with thickness at inferior border of bar and flat on the tissue side. Advantage of lingual bar are make patients less annoying than others, not trap food particle, not impinge oral tissue when restoration is rotate in function and is placed or removed and not cover oral tissue so easier to cleansing

Introduction: ¬Periodontium accredit to the specialized tissues that surround and support the teeth, and maintains them in the maxillary and mandibular bones. Periodontium is the anatomic assemblage of tissue, investing and supporting the tooth. The word comes from the Greek terms peri-, means "around" and -odons, means "tooth."1 In actual sense it means that which is "around the tooth". It provides the abutment all-important to advance teeth in function. The capital functions of periodontium is

General description of the injury: This injury is the stretching of ulnar nerve that runs through cubital tunnel, which is is the largest unprotected nerve on the body. The nerve can tear when the ulnar nerve is compressed. It is between the medial epicondyle and olecranon, and runs along the ulnar bone. For the muscles, the cubital tunnel is adjacent to to triceps and continues down the forearm between the flexor carpi ulnaris muscle.It can be either chronic or acute, but it typically acute. It

settle down. Then without notice I break out into tears. Scene 7 While I was sobbing Alpha, went to grab the tissue box for me. “Here sir,” Alpha says as he hands me the tissue box. “Thank you Alpha,” I respond still in tears. “Sir when you are ready, there is something I need to show you in the living room,” Alpha says while he walks into the living room while I throw out my used tissues, when walking towards the living room I see a Blue glow coming from Alpha 's chest. I get closer and my jaw completely

collection of them form the tissue. Tissue is a group of cells that is highly organized manner according to the specific function and structure which then make up organs and various part of body. (Slomianka, 2009)There are four types of tissues that make up the human body, which is epithelial tissue, connective tissue, muscle tissue and neural tissue. However, the tissue that gives support to the body and made up the bones is connective tissue. The functions of connective tissues are giving the structural

plants, and are considered a process of evolution as they have evolved in order to adapt to the change in the environment. In this investigation we will be observing the results of both types of plants under harsh conditions. It is preferable that the Polyploidy plant will survive harsher conditions as they have actually developed due to the change in their biosphere therefore making it more likely that they will survive unfavourable conditions. In this experiment we will be taking a look at which

What are tonsils? The tonsils are tissue masses that are found at the point where the mouth and throat meet. There is one tonsil on each side of the throat. The tonsils are part of the human immune system. The immune system is what helps to fight off germs that can cause a variety of illnesses. They are there to process germs and help the body recognize different types of germs so that they can be fought off. Will my child 's immune system be weaker if the tonsils are removed? The immune system

Task 2 4 main tissue types Epithelial tissue: this type of tissue covers the entire surface of the human body and is made up of very closely packed cells that are either one or more layers thick. Epithelial tissue also covers or lines the internal body surfaces. There are two different types of epithelial tissue these are simple epithelium or stratified epithelium. Simple epithelium is only one cell thick whereas stratified epithelium is two or more cells thick. Simple epithelium can be separated

The small intestine consists in four layers: serosa, muscolaris, submucosa and mucosa; this last one consists of three different sublayers: muscolaris mucosa, lamina propria and epithelium. The lamina propria forms the supporting layer of the epithelium and is populated by extracellular matrix producing cells, neurons, smooth muscle fibres and immune cells. The epithelial layer is made up of a single-layered epithelium consist of four cell types: enterocytes, goblet cells, Paneth cells and enteroendocrine

gelatinous structure present in the centre and is contained in the periphery by annulus which is collagenous and cartilaginous, and two cartilaginous endplates cephalad and caudad. Collagen fibers from annulus continue and attach to the surrounding tissues, tying into the vertebral body along its rim, cartilaginous endplates superiorly and inferiorly and anterior and posterior longitudinal ligaments. Bony endplate and cartilaginous endplates were connected by calcified cartilage. At birth, the disc

The organs in a human body are made of a structure called tissue which is also made of cells with similar functions. Tissues are commonly categorized by the function of the cells that make them up. There are four types of tissues in the human body which are nervous, epithelial, muscular, and connective. The main components that make up nervous tissue are nerve cells or neurons. An important structure of nervous tissue are the neuroglial cells. Neurons are a specialized type of cell that receive and
