What are the three different tissue layers and how you distinguish between them?
The three germ layers are the endoderm, the ectoderm, and the mesoderm. Cells in each germ layer differentiate into tissues and embryonic organs. The ectoderm gives rise to the nervous system and the epidermis, among other tissues. The mesoderm gives rise to the muscle cells and connective tissue in the body.
What are the similarities and differences between epithelial and connective tissue?
The key difference between epithelium and connective tissue is that epithelium is the tissue that lines outer surfaces of organs and blood vessels as well as inner surfaces of cavities of organs while connective tissue is the tissue that separates, connects and supports various tissues and organs in an animal body.
What are muscle tissues how is the function of this tissue related to the typical characteristics of its cells?
1 Answer. Muscle tissues are tissues made of cells able to perform contractions and thus to generate movement. The function of the muscle tissue is to pull bones (skeletal striated muscle), to contract and move viscera and vessels (smooth muscle) and to make the heart to beat (cardiac striated muscle).
What are three general characteristics of connective tissues?
What are characteristics of connective tissues? Share three basic components: (1) specialized cells, (2) extracellular protein fibers and (3) a fluid known as ground substance.
What are the 3 embryonic tissues?
germ layer, any of three primary cell layers, formed in the earliest stages of embryonic development, consisting of the endoderm (inner layer), the ectoderm (outer layer), and the mesoderm (middle layer).
What are the three types of tissues?
Overview. There are 4 basic types of tissue: connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body).
What is the difference between connective tissue and muscle tissue?
The key difference between connective tissue and muscle tissue is the functions of each tissue. The main function of connective tissue is to connect the organs in the body. In contrast, the main function of muscle tissue is to facilitate movement and to provide protection to the internal organs of the body.
What’s the difference between epithelial and muscle tissues?
Epithelial tissue provides a covering (skin, the linings of the various passages inside the body). Muscle tissue includes striated (also called voluntary) muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach.
What are the three types of muscular tissue for each describe the cell shape the type of control voluntary or involuntary and the presence or absence of striations?
Overview. The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
What are the 3 types of connective tissue?
Connective tissue can further be broken down into three categories: loose connective tissue, dense connective tissue, and specialized connective tissue. Loose connective tissue works to hold organs in place and is made up of extracellular matrix and collagenous, elastic and reticular fibers.
What are the 3 major connective tissue cell types?
Connective tissue cells are able to reproduce but not as rapidly as epithelial cells. Most connective tissues have a good blood supply but some do not. Numerous cell types are found in connective tissue. Three of the most common are the fibroblast, macrophage, and mast cell.
What features distinguish the three types of muscular tissue?
Skeletal Muscle Tissue. These muscles are attached to the skeleton and help in its movement.
How do three muscle tissue types look similar and different?
Muscle tissue is easily distinguishable by its highly organized bundles of cells. Although there are three types of muscle tissue with unique cell morphologies, the fiber bundles of each tissue type are arranged in parallel oriented on the long axis and are distinct from surrounding connective tissue. Muscle is classified according to the appearance of the contractile cells.
What are three types of muscles and their function?
Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth (Table 1). Skeletal muscle is attached to bones and its contraction makes possible locomotion, facial expressions, posture, and other voluntary movements of the body.
What are the four types of muscle tissue?
Muscle Tissues- These are of three types, smooth muscle tissue- found in inner linings of organs, skeletal muscle tissue- found attached to the bone and helps in body movement and cardiac muscle tissue- found in the heart. These tissues help in changing the size of a cell. Nervous Tissues- Made up of neurons (nerve cells in the brain), these
