ANAT1005 Lecture Notes - Lecture 2: Connective Tissue, Epithelium, Cardiac Muscle
Document Summary
Cells are the smallest living unit in the body. The study of cells is known as cytology. The structure of cells reflect the specialisation in function. A tissue is a group of cells of similar structure that work together to perform a common function. Most organs contain all 4 types of tissues, (cmen. Covers the surface of the body, body cavities and internal organs. Occurs at the boundary between 2 different environments. Cancers that arise from epithelium tissue are called carcinomas. The epidermis of the skin covers the entire surface of the body. Mucosa lines body surfaces that are exposed to the external envion. Endothelium covers the lumen all blood and lymphatic vessels. Characterised by some type of ground substance embedded with protein fibres. Nerve tissue is the main component of the nervous system (brain, spinal cord and nerves) Glial are supporting cells anterior- towards the front. Cranial- towards the sky and caudal- towards the tail.
