what do connective tissues do | connective tissues connect various parts of the body |
The four tissue types | 1) Epithelial Tissue 2) Connective tissue 3) Nervous tissue 4) Muscle Tissues |
What do Epithelial Tissues do | 1) Protection 2) Absorption 3) Filtration 4) Secretion: |
Are there different types of epithelial tissue? | Epithelial Tissue is classified by the shape of the cells and the number of layers it has. |
The Number of Layers | 1) Simple Epithelial Tissue will have a single layer of cells. 2) Stratified Epithelia will have several (multiple) layers. |
The Shape of its Cells | 1) Squamous: These are flat cells that resemble fish scales. In fact, “squam” means scale. 2) Cuboidal: shaped like dice or sugar cubes. 3) Columnar: as the name implies, these cells are tall and cylindrical. |
The three classifications of muscle tissue include | 1. Skeletal –attached to bones. E.g. triceps and biceps 2. Cardiac- Heart Muscle 3. Smooth – Abdominal Muscles, for example. |
Identify the 4 types of membranes found in the body. | 1) cutaneous membranes; 2) serous membrane 3) mucous membranes; and 4) synovial membranes. |
What body cavities are lined by serous membranes and synovial membranes? | 1)covers the lungs 2)covers the abdominal/organs 3)covers the heart |
The three classifications of muscle tissue | 1. Skeletal –attached to bones. E.g. triceps and biceps 2. Cardiac- Heart Muscle 3. Smooth – Abdominal Muscles, for example. |
What does synovial fluid do and where is it found? | The synovial fluid lubricates the ends of the bones allowing them to move freely. |
what are the three function | 1) movement 2) protection 3) heat |
What can a person’s skin color tell us | 1) Lighter complexion -skin cancer 2) Cyanosis-circulatory breathing issues 3) Redness-inflammation 4) Pallor (pale)-fear 5) Jaundice - liver disorder 6) Excessive bruising -lack of Vitamin C |
what is necrosis | tissues death |
outline the steps in tissue repair | the first is by regeneration and the second by fibrosis |
microbes what are they | forms of life and they live and grow everywhere |
pathogenic vs non pathogenic | non pathogenic are harmless and pathogenic are harmful |
what is another name for cutaneous membrane | it is called skin |
identify the 4 types of microbes | 1)bacteria 2)viruses 3)fungus 4)protozoa |
what are the ideal growth conditions for bacteria | 1)host 2)warmth 3)darkness 4)oxygen 5)moisture 6)food |
what is the main function of nervous tissue and it's primary properties? | its primary properties are irritability (the capacity to various physical and chemical agents) and conductivity (the ability to transmit the resulting reaction from one point to another) |
What is the main difference between Endocrine Glands and Exocrine Glands? Give an example of each type. | The dermis contains exocrine glands (remember what these are). These include sweat glands and sebaceous glands |
Describe the effects of aging on our tissues. | as skin ages it becomes thinner |
What is the permanent replacement of normal tissue with scar tissue called? | it calls fibrosis |
the primary functions of the skin include | 1 protection 2 regulate temperature 3 synthesize vitamin d 4 trigger Immune response repair mechanisms 5 store fats 6 excrete wastes 7 produce melanin |
what is skin cancer called? | Melanoma |
What is the skin’s natural “sunblock” called | Melanocytes, another type of skin cell, protect the skin by producing the brown pigment melanin, which helps filter ultraviolet (UV) light (irradiation) |
skeletal system | has two parts 1 axial skeleton 2 appendicular skeleton |
