Transcript of Tissue Types
The muscle tissue is split up into skeletal, smooth, and cardiac tissue.
The epithelial tissue is the largest category of tissue, it covers the outsides and insides of body surfaces. It's so condensed because it provides a barrier, and also absorbs nutrients from connective tissues, which is why you have so many different layers and types of epithelial tissue.
The function of epithelial tissue is to protect, from radiation, traumas, and patogens, which is why it is so thick. It also helps in secretion, absorption, and sensation.
The three types of epithelial tissue, squamous, cuboidal, and columnar, are seperated by layers, which is simple and stratified.
The main component of the nervous system, found in the brain and spinal cord. Nervous tissue is made to react to stimuli. It is composed of neurons which recieve and transmit impulses throughout the body. The neurons that make up the nervous tissue recieve and transmit impulses. The functions of the nervous tissue is to help the nervous system in control of muscles, senses, homeostasis, glands, and mental activity.
All facts came from the lesson 2 presentation on NCVPS
Connective tissue is the most abundant tissue in the body, and is made up of bones, cartliage, dense and loose tissue, and blood. It either connects, supports, or seperates the organs and tissues in the body.
This connective tissue connects and binds the bones together to cushion and support the body. The cartilage is at the end of the bone and connects while the blood runs through the body.
The bottom left is skeletal tissue which is voluntary and controls the movement in your body. Skeletal tissue is composed of tendons that attach to bone to help move it and keep it supported
The bottom right is cardiac tissue, which is located in the heart a controls the heartbeat. Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels and circulatory system.
The top is smooth tissue, which lines the organ and blood vessel walls. Smooth muscle tissue is involuntary, and is made up of individual cells to give gradual responses and control.
Neurons are very wiry because they spread throughtout the body to transmit actions and impulses. Nervous tissue is very sensitive and are made up of neutrons.
I believe Epithelial tissue is the best tissue type for function and location. It covers the outside of the body and is very thick, which is helpful for protection against accidents to UV radiation and pathogens entering the body. The different kinds of protection and layers is why you have so many categories of epethelial tissue like squamous, cuboidal, and columnar. It doesn't recieve blood directly, but recieves nutrients through connective tissues. Glands are formed from the infolding of epithelial tissue and subsequent growth in the connective tissue underneath it. This creates the two major gland classes, exocrine and endocrine glands. Both of these gland types secrete their product either internally or externally.
