Medical Terminology: Names of Physical Conditions Affecting Skin, Bones, Muscles, or Senses By Beverley Henderson, Jennifer Lee Dorsey Your bones, muscles, skin, and senses form an intricate network that holds your body up, keeps it moving, protects it, and brings messages to your brain that help it function.

The human musculoskeletal system (also known as the locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal musculoskeletal system provides form, support, stability, and movement to the body.

It is made up of the bones of the skeleton, muscles, cartilage, tendons, ligaments, FMA: Human body, the physical substance of the human organism. Characteristic of the vertebrate form, the human body has an internal skeleton with a backbone, and, as with the mammalian form, it has hair and mammary glands.

Learn more about the composition, form, and physical adaptations of the human body. These cells are organized into four basic tissues that, in turn, are assembled to form organs.

When you examine tissue at a microscopic level, having the ability to detect the presence and location of the four basic tissues enables you to identify the organ that you are looking at.

Dermis: This lower layer of the skin contains collagen and elastic fibers that give strength to the skin. This layer is also where the vasculature and nerves live. Together the epidermis and dermis form the cutaneous layer. The subcutaneous layer (area below the skin) lies underneath the cutaneous layer and is sometimes called the hypodermis or superficial fascia.

Animals developed external or internal skeletons to provide support, skin to prevent or lessen water loss, muscles that allowed them to move in search of food, brains and nervous systems for integration of stimuli, and internal digestive systems.

Organs in animals are composed of a number of different tissue types. to the muscles so when you wish to pick up a glass the motor nerves tell the muscles of the hand, arm, Bones and chest to move. Fig Peripheral Nervous System including Motor (Voluntary) Nerve and Sensory Nerves 3. The Autonomic (involuntary) Nervous System controls activity in the body without involving the conscious mind.

Foot Definition. The foot is a part of vertebrate anatomy which serves the purpose of supporting the animal’s weight and allowing for locomotion on land. In humans, the foot is one of the most complex structures in the body.

It is made up of over moving parts – bones, muscles, tendons, and ligaments designed to allow the foot to balance the body’s weight on.

When discussing equine anatomy, what better place to start than with the skin, the horse’s largest organ, ranging from % of the animal’s total weight depending on age.

It serves a number. Bones have many functions, including the following: Support: Bones provide a framework for the attachment of muscles and other tissues. Protection: Bones such as the skull and rib cage protect internal organs from injury.

Movement: Bones enable body movements by acting as levers and points of attachment for muscles. The human body is an amazing structure which contains a wide range of complex parts and processes.

The facial muscles are a group of about 20 flat skeletal muscles lying under the facial skin in the of them originate from the skull or fibrous structures and radiate to the skin through an elastic tendon. Contrary to the other skeletal muscles they are not surrounded by a fascia (except the buccinator).The facial muscles are positioned around facial openings.

Mesoderm, the middle of the three germ layers, or masses of cells (lying between the ectoderm and endoderm), which appears early in the development of an animal embryo. In vertebrates it subsequently gives rise to muscle, connective tissue, cartilage, bone, notochord, blood, bone marrow, lymphoid.

Anatomy: A Complete Guide for Artists. I like a lot of the Dover books because they’re often very high quality and surprisingly affordable. Anatomy: A Complete Guide for Artists is a somewhat older book dating back to the early s. Thankfully the human figure hasn’t changed much since the late 20th century so all the information is still applicable.

The thinnest parts of skin are behind their ears, around their eyes, on the chest, abdomen and shoulders. On these parts, their skin is as thin as paper. Skin provides a protective function for all animals, however, there are some unique characteristics about the elephants skin.

Elephants skin is very sensitive to the sun. Muscle is the most abundant tissue in most animals, and muscle contraction accounts for most of the energy-consuming cellular work in active animals. There are three types of muscle tissue in the vertebrate body: skeletal muscle, cardiac muscle, and smooth muscle.

Attached to bones by tendons, skeletal muscle is responsible for voluntary movements. The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault ().The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.

Tendons connect muscles to bones. Tendons help form a connection between soft contracting muscle cells to hard bone cells.

Muscle Memory When we practice an action over and over again, we get what is called muscle memory. It allows us to become more skilled at certain activities such as sports and music.

Spongy bone is made of tiny plates called trabeculae, which serve as struts, giving the spongy bone strength. Figure \(\PageIndex{1}\): Bone structure: (a) Compact bone is a dense matrix on the outer surface of bone.

Spongy bone, inside the compact bone, is porous with web-like trabeculae.

(b) Compact bone is organized into rings called osteons. Animal studies proved the efficacy of LIV on bone endpoints by avoiding human study limitations of age, sex, hormonal status, and comorbidity.

For instance, adult sheep exposed to daily LIV (30 Hz, g, 20 min) showed a 34% increase in femoral trabecular bone by micro-computed tomography and histology at 1 year [ 39, 40 ].

Learn how to recognize and provide first aid treatment for a suspected fracture. © Karen Carlton – Bones & Muscles Science Unit, Page - 5 Day 2 Objectives: To demonstrate understanding of the skeletal system by designing a reproduction of the bone structure.

Supplies: Quiz, overhead bone chart, poster board, bone charts for each student from yesterday, brads or glue. Give the students the fun quiz – next page. There are 3 types of muscle tissues in all the animal tissues and you’ll learn them shortly.

As previously mentioned muscle tissue has the ability of contraction and expansion. That’s what makes you move of one part of the body relative to the other part.

Stratified Muscle Tissues. These muscles are identified as skeletal or voluntary muscles. The red marrow of some bones is an important site for hematopoeisis or blood cell production that replaces cells that have been destroyed by the liver.

Here, all erythrocytes, platelets, and most leukocytes form in bone marrow from where they migrate to the circulation.

Muscular System. Muscles contract (shorten) to move the bone attached at. Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight. Bones also protect the body's organs.

The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone. This chicken has black bones, organs, and meat: Here’s why. There are four breeds of chicken that have black insides, and all of them possess the same genetic mutation.

A scientist explains how. In the diagrams below, I'll be showing muscle groups in color, with a black line to show the forms that would show through the skin (I also show protruding bones that would do the same). We all have a layer of fatty tissue under our skin, and this softens the look of the underlying muscles.

The skin comes in all kinds of textures and forms. There is the dry warty skin of toads and crocodiles, the wet slimy skin of fish and frogs, the hard shell of tortoises and the soft supple skin of snakes and humans.

Mammalian skin is covered with hair, that of birds with feathers, and fish and reptiles have scales.Skeletal muscles are attached to bones, therefore when the associated muscles contract they cause bones to move. 4. Storage of Minerals. Bone tissues store several minerals, including calcium (Ca) and phosphorus (P).

When required, bone releases minerals into the blood - facilitating the balance of minerals in the body. 5. Production of Blood Cells. The skull, humerus (arm bone), pelvis and collar bones are examples; Medullary: These bones store calcium.

In the centers of these bones is bone marrow which makes blood cells. Legs, shoulder blades and ribs are examples of this type. The neck and backbone of the chicken is very flexible. The spine contains 39 bones with the neck being quite long.
