Every organelle of a muscle fiber is arranged to ensure form meets function
Skeletal muscles are attached to bones by collagen fibers called tendons
Under control of the somatic nervous system
The Cardiac muscle cells unlike most other tissues depend on blood to deliver blood and nutrients while getting rid of Carbon Dioxide
The cells that the Cardiac muscle are made up of only have three nuclei
The cardiac muscle is found on the walls and histological foundation of the heart
Either the whole muscle contracts or the whole muscle relaxes. That is the case with this tissue and it is called being of the single unit variety.
Smooth muscle tissue are found within the walls of blood vessels also in the male and female reproductive tracts
Involuntary non striated muscle
Facts
Adipose tissue is more commonly known as body fat
loos connetive tissue made up of adopoctyes
Function: Insulates, protects and supports organs. Stores energy
Location: Under the skin, around kidneys and eyes, in abdoman and in breats
Function: Transports oxygen through the body, helps with immune system and protects the body from infection and disease
Location: Blood
contains proteins mixed with water to make gel
Three different types of cartilage, Hyline, elastic and Fibrocartilage
contains a lot of elastic protein fibers which makes it very flexable
Function: Provides stiff but somewhat flexible support and reduces friction between bony surfaces
Location: Tips of ribs, sternum, larynx, trachea, bronchi and part of nasal septum
red bone marrow is found in the spongy bone
filled with central canals which are surrounded by cells
Location: Bone
Function: Provides support and protects the organs
Function: Helps pump blood throughout the body
Location: Lungs; between vertebrae of spinal column, ligaments suporting penis and transitional epithelia, blood vessel walls, permits expansion and contractions of organs
Location: Lymph nodes, spleen and bone marrow
Function: Forms structural framework of organs like lymph nodes, spleen, thymus, and bone marrow.
Regulaur
Function: Connection and protection
Location: tendons, ligaments, ligaments between vertebrae, along dorsal neck and vocal cords
Irregulaur
Location: Fibrous capsules of organs and joints and dermis of skin
Function: Withstand tension and provide stuctural strength
Function: Most widespread connective tissue; contains all cell and fiber framework; makes up volume
Location: Between tissues and organs, superficial fascia, and under epithelial tissue
fibroblast cells are in the loose connective tissue and they secrete strong fibrous proteins
Made up of multiple layers of cube shaped cells
Location: Large ducts of sweat glands,mammary glands and salviary glands
Function: Protection
Location: Small amounts in male urethra and in large glands
It is a very rare type of epithelial tissue
composed of column shaped cells arranged in multiple different layers
Function: Protection and secretion
Function: Protects underlying tissue in areas subject to abrasion
Location: Esophagus and mouth
Non-Keratinized surfaces do not have Keratin so they must be kept moist by bodily secretions
Keratinized surfaces are protected by Keratin
Divided into two parts Keratinized and non-keratinized
Function: Abosrbtion, secretion of mucus, enzymes and other substances
Facts:
Non-ciliated are found lining the gastrointestinal tract
Ciliated moves mucus and is in the upper respiratory tract
Simple columnar epithelium are split into two parts, Ciliated and non-ciliated
It is a uni-layered epithelium meaning that it has one layer to it
Location: Anal canal, stomach, gallbladder and uterine tubes
The cells either are active or passive depending on the location
A single layered epithelium made up of cube like cells. The cells have large, spherical, and central nuclei
Location: Kidney tubules, small galnds and ovary surface
Function: Secretion and absorbtion
3 Facts:
Single layer of flat cells in contact with the basement membrane
Function: Allows passage of materials by diffusion and filtration in sites where protection is not important
Location: Mouth, Anal Canal and Mouth
