The tissue consist of an extensive network of fibers secreted by cells called fibroblasts. The most numerous of these fibers are the thicker, lightly-staining collagenous fibers. Thinner, dark-staining elastic fibers composed of the protein elastin can also be seen.

The cells that make the reticular fibers are fibroblasts called reticular cells. Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow. You will never see reticular connective tissue alone--there will always be other cells scattered among the reticular cells and reticular fibers. https://www.middlesex.mass.edu/rlolibrary/RLOs/154/Reticular. gif http://www.mhhe.com/biosci/ap/histology_mh /reticct.jpg http://www.austincc.edu/histologyhelp/tissues/images/tk100.jpg Dense Regular Dense connective tissue is characterized by an abundance of fibres with fewer cells, as compared to the loose connective tissue. It is also called fibrous or collagenous connective tissue because of the abundance of collagen (collagenous) fibres. Little intercellular substance is present. Furthermore, in this tissue type, the fibres are organized in a regular, parallel pattern (Figure 12). Hence, the name ± dense regular (fibrous or collagenous) connective tissue. http://www.myspeedtest.com/bioimage/OldSlides/bio231histo400 x300/Dense%20Regular%20Connective%20Tissue%20x100.J http://kentsimmons.uwinnipeg.ca/cm1504/15lab42006/lb4pg6_fil es/image013.jpg http://www.cytochemistry.net/microanatomy/connective_tissue/0 0004525.jpg http://utpa.net/Connective%20Tissue/projections/dense%20regu Irregular Dense irregular connective tissue consists predominantly of randomly arranged collagen fibers and a few fibroblasts.

Muscle Skeletal

Skeletal muscles form the flesh sometimes referred to as the red meat of an animals body They are attached to and result in the movement of the bones of the skeleton A typical skeletal muscle

cell is a highly modified giant multi-nucleate cell (fibre) Each fibre is cylindrical in shape with blunt rounded ends The flattened nuclei are located mainly at the periphery of the cell just inside the sarcolemma The cross-striped (or striated) appearance of light and dark banding results from the arrangement of myofibrils small

protein contractile units embedded in the sarcoplasm

Smooth

Smooth muscle is abundant throughout the internal organs of the body especially in regions such as the digestive tract As its

contraction is not under conscious nervous control it is referred to as involuntary muscle Smooth muscle fibres are spindle-shaped

structures with a prominent centrally located nucleus In comparison with skeletal muscle fibres they are much shorter in

length and they do not exhibit striations The cells occur as individual fibres within organs or as groups of fibres closely

interlaced in sheets or bands

Cardiac

Cardiac muscle is a highly specialized tissue restricted to the wall of the heart It is also an involuntary type of muscle as its

contraction is not consciously controlled Unlike smooth or striated fibres cardiac fibres tend to form long chains of cells which branch and intertwine This arrangement results in the peculiar wringing

action of the heart The junction of one cell with another in a particular chain is known as an intercalated disc and appears as a heavy dark line running across the fibre Each cell has a somewhat cylindrical shape with one centrally-located oval nucleus Cross-striations are apparent but they are not as regular nor as prominent

as those of skeletal muscle

Muscle Skeletal

Skeletal muscles form the flesh sometimes referred to as the red meat of an animals body They are attached to and result in the movement of the bones of the skeleton A typical skeletal muscle

cell is a highly modified giant multi-nucleate cell (fibre) Each fibre is cylindrical in shape with blunt rounded ends The flattened nuclei are located mainly at the periphery of the cell just inside the sarcolemma The cross-striped (or striated) appearance of light and dark banding results from the arrangement of myofibrils small

protein contractile units embedded in the sarcoplasm

Smooth

Smooth muscle is abundant throughout the internal organs of the body especially in regions such as the digestive tract As its

contraction is not under conscious nervous control it is referred to as involuntary muscle Smooth muscle fibres are spindle-shaped

structures with a prominent centrally located nucleus In comparison with skeletal muscle fibres they are much shorter in

length and they do not exhibit striations The cells occur as individual fibres within organs or as groups of fibres closely

interlaced in sheets or bands

Cardiac

Cardiac muscle is a highly specialized tissue restricted to the wall of the heart It is also an involuntary type of muscle as its

contraction is not consciously controlled Unlike smooth or striated fibres cardiac fibres tend to form long chains of cells which branch and intertwine This arrangement results in the peculiar wringing

action of the heart The junction of one cell with another in a particular chain is known as an intercalated disc and appears as a heavy dark line running across the fibre Each cell has a somewhat cylindrical shape with one centrally-located oval nucleus Cross-striations are apparent but they are not as regular nor as prominent

as those of skeletal muscle

NeurogliaPeripheral

2 types Satellite

Glial cells commonly called neuroglia or simply glia are one of two major classes of cells in neural tissues the other being neurons for

which the glial cells provide support Glial cells surround neurons hold them in place provide nutrition (nutrients and oxygen) help

maintain homeostasis provide electrical insulation destroy pathogens regulate neuronal repair and the removal dead neurons

and participate in signal transmission in the nervous system
