Summary of Animal Tissues

00:00:00 - 00:25:00

This video covers the different types of tissues in the human body, with a focus on the tissues found in the heart. Cardiac muscle is the only muscle in the body that can move on its own, and its specific movement is due to its connections to the bones and the spinal cord. Squamous epithelium, columnar epithelium, and elongated cells are all found in the cardiac muscle, and these cells produce substances that help it to function. Sensory neurons and motor neurons are also discussed.

• 00:00:00 Epithelial tissue is a simple tissue found in specific locations on the body, and its primary function is to protect the body from outside elements. Epithelial tissue is composed of cells that are generally square-shaped, and it has a flattened nucleus. Squamous epithelium is the most common type of epithelial tissue, and it is found in the lining of the mouth, alveoli, and the skin. Squamous epithelium is very quick to heal, and it needs to do so in order to keep from losing its protective function.
• 00:05:00 In this video, the different types of epithelial cells are examined. Sensory neurons, which are responsible for sensing various stimuli, are highlighted. The different parts of a sensory neuron are discussed, and the difference in their structures is highlighted.
• 00:10:00 This video discusses the different types of connective tissues and their functions. It starts with a description of the dendrite, axon, and cell body regions of a motor neuron, and goes on to discuss the different types of connective tissues. Connective tissues include tissues that support and stabilize organs, and can be either liquid or semi-liquid.
• 00:15:00 This video discusses the different types of connective tissue, and explains that areolar tissue is a very basic tissue that binds epithelium. It is often found between organs and attaches organs loosely. Fibrous connective tissue is a more neatly arranged type of connective tissue that provides strength and flexibility. Blood is the only liquid connective tissue, and it carries chemical messages around the body. Adipose tissue is made mostly of fat cells, and is found throughout the body.
• 00:20:00 Adipose tissue provides insulation, cushioning, and flexibility for the body. Bone is the main source of skeletal muscle tissue, and it also allows for muscle attachment. Smooth muscle is responsible for involuntary movement, while cardiac muscle is responsible for the pumping of blood.
