Thick skin is only found in areas where there is a lot of abrasion - fingertips, palms and the soles of your feet. This is a picture of an H&E stained section of the epidermis of thin skin. There are only four layers in the epidermis of thin skin. The stratum lucidum layer is absent.

areolar Location: subcutaneous layer deep to skin, superficial part of dermis of skin, mucous membranes, blood vessels - Function: strength, elasticity, support adipose Location: subcutaneous layer deep to skin, heart and kidneys -Function: reduces heat loss through skin, preserves energy, supports and proteccts reticular Location: stroma of liver, spleen, lympnodes, basement membrane - Function: forms stroma of organs, binds together smooth muscle tissue cells Dense regular Location: forms tendons, ligaments, aponeuroses - Function: strong attachment btw various structures Dense Irregular Location: Fasciae, deeper part of dermis of skin, periosteum of bone, heart valves - Function: Strength Elastic Location: lung tissue, walls of elastic arteries, trachea, bronchial tubes, vocal cords - Function: stretching Hyaline cartilage Location: ends of long bones, ribs, nose, larynx - Function: smooth surfaces, flexibility, support Fibro cartilage Location: pubic symphysis, intervertabral discs, menisci of knee, tendons - Function: support and rigidity Elastic Cartilage Location: Epiglottis, auricle, auditory tubes - Function: support and maintains shape Compact bone Location: makes up various parts of bones - Function: support, protection, storage, houses blood forming tissue, serves as levers that act together with muscle tissue to enable movement Blood Location: within blood vessels, chambers of heart, arteries, veins - Function: red BC's transport Oxygen and CO2, white BC's carry on phagocytosis and are related to allergic reactions and immunce system responses.
What are the types of connective tissue and where are they located?

Bone and blood represent different types of connective tissue because both have ground substances, cells and fibers. ... Membranes are composed of epithelial and connective tissue. Mucus membranes also helps to absorb nutrients and lubricate surfaces.
Why are bone and blood considered connective tissues?
300
Cutaneous Membrane The skin, covering outer surface of body Mucus Membrane aka Mucosa, lines the inside of every hollow internal organ that opens to outside of the body all are wet to moist, and secrete mucus, consist of epithelial sheet under lain by layer of loose connective tissue Serous Membrane Slippery membranes that line the closed pleural, peritoneal, and pericardial cavities, consist of thin layer of epithelium(mesothelium) over a thin layer of areolar tissue
What are the 3 types of covering and lining membranes?

The difference between it and hyaline is that fibrous cartilage has a much denser matrix which contains far fewer chondrocytes and thicker collagen fibres. The main function of fibrocartilage is to serve as a shock absorber for structures where excessive pressures are generated
What is the difference between hyaline, elastic, and fibrocartilage?

The human skin (integument) is composed of at least two major layers of tissue: the epidermis and dermis. ... Beneath this, the dermis comprises two sections, the papillary and reticular layers, and contains connective tissues, vessels, glands, follicles, hair roots, sensory nerve endings, and muscular tissue
What are the 3 layers of the integument? What is each composed of?

Both use ion channels to move ions across the cell membrane, in or out of the cell. Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.
What is the main difference between passive and active transport?

Human blood contains a buffer of carbonic acid (H 2CO 3) and bicarbonate anion (HCO 3 -) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death.
Name an example of a buffer in the human body.

All connective tissue consists of three main components: fibers (elastic and collagenous fibers), ground substance and cells. Not all authorities include blood or lymph as connective tissue because they lack the fiber component. All are immersed in the body water.
What are the three main components of connective tissue?

Isotonic, Hypotonic, and Hypertonic Solutions. Water moves readily across cell membranes through special protein-lined channels, and if the total concentration of all dissolved solutes is not equal on both sides, there will be net movement of water molecules into or out of the cell.
How does a cell respond in a hypotonic solution? Hypertonic solution? Isotonic solution?

Like all complex animals, humans must maintain a core set of necessary life functions to survive. These include maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and grow. In order to survive, humans also need nutrients, oxygen, water and an appropriate atmosphere.
What are the necessary life functions?

Students of anatomy learn about the structure of body parts, while those enrolled in physiology study the functions and relationships of body parts. While these two fields are often paired together in the same class or program title, they may also be offered separately.

5 Basic Needs to Survive and Thrive. In extreme conditions, a human can survive 3 minutes without air, 3 hours without shelter, 3 days without water, and 3 weeks without food. Oxygen in one of the most essential human needs. Our bodies need a consistent supply of it to function properly
What are the survival needs for a human?

A positive feedback loop causes a self-amplifying cycle where a physiological change leads to even greater change in the same direction. A negative feedback loop is a process in which the body senses a change, and activates mechanisms to reverse that change.
What is the difference between positive and negative feedback?
