Cell Arangement
Simple Pseudostratified- one cell layer
Stratified-many cell layers
Cell Shapes
Squamous-flat cells taller than broad
Cubodial-cube shaped cells, as broad as tall, with rounded central nuclei.
Connective Tissue
Made up of two main tissues collagen and elastin, main functions are mechanical support of the body, binding and
packaging, protective padding and insulation, transport of essential materials, protection against infection.
Ordinary Connective Tissue-
i. Loose/areola- tissue contains a jelly like matrix with a loose fibre network.
ii. Adipose- Tissure is similar to areolar tissue but is mostly filled with large fat storing cells.
iii. Dense/fibrous-tissue in whch fibres prdominate two types regular and irregular.
Skeletal Connective Tissue-
Cartilage- the cells lie in fulied filled spaces in the matrix. The matrix is firm and plastic with a fibrous network.
i. Hylaine Cartilage-transuletn matrix, fine collaged fibres not easily seen,
ii. Fibro Cartilage- dense network of collagen fibres in matrix.
iii. Electric Cartilage-dense network of elastic fibres.
Bone-the matrix is solid and rigid with a fibrous network and mineral crystals.
i. Compact Bone-composed of concentric cylinders of bony tissue
ii. Spongy Bone-interconnected narrow bars of bone with marrow in between.
Blood and Lymphatic Tissue
i. Haemopoietic Tissure-blood forming tissue
ii. Myeloid-red marrow
iii. Lymphoid eg spleen, lymph nodes
iv. Blood and Lymph-the matrix is a fluid plasma various cells being suspended in plasma
Muscular Tissue
i. Skeletal Muscle-associated with the skeleton, contracting muscle cells exert a pull on the bone so enabling
ii. Smooth Muscle- movement of internal organs, are bought about by smooth muscle tissure located within the
organs. Smooth muscle cells are enlongated and spindle shaped with a single central nucleus and no visible
iii. Cardiac Muscle-found in the wall of the heart. Each cell is striated and has a c entral nucleus.
