Tissue

Muscular (Contractile) Tissue

Function

Moves the body and its parts

Types

Skeletal Muscle a.k.a. voluntary muscle, Found: Attached by tendons to the bones of the skeleton (when it contracts, body moves), Apperance: Cylindrical an long with the nuclei located at the periphery of the cell

Smooth (Visceral) Muscle, Unlike skeletal muscle, muscle is involuntary (not under voluntary control), is slower to contract but stays contracted for a longer period of time, Found: In the walls of the intestine, stomach, and other internal organs. As well as, found in blood vessels

Cardiac Muscle, Found: only in the walls of the heart (contraction controls heartbeat), Appearance: branched cells, have single (central) nucleus, has striations

Appearance/ Composition

Composed of muscle fibers (cells) which contain actin filaments and myosin filaments (cause movement)

Connective Tissue

Function

Binds organs together, provides support and protection, fills spaces, produces blood cells, and stores fat, i.e. Protection for epithelium and internal organs, Can form protective covering, Connect muscles to bones, and bones to other bones and joints

Found

In the lungs, arteries, urinary bladder, internal organs, tendons, ligaments, beneath the skin, around the kidneys, on the surface of the heart, lymph nodes

Are cartilage, bones, and blood

Types

Differ according to thype of matrix and the abundance of fibers in the matrix, Loose Fibrous and Dense Fibrous Tissues, Adipose Tissue and Reticular Connective Tissue, Cartilage, Bone, Blood, Not all people classify this as a connective tissue (vascular tissue instead)

Appearance/ Composition

Are widely seperated by a matrix (made up of a noncellular material that can vary from being solid to semifluid to fluid

Connective Tissue

Nervuous Tissue

Function

Recieves stimuli and conducts nerve impulses, Nervous system has three functions: sensory input, integration of data, and motor outout

Found

In the brain and spinal cord (nervous system)

Appearance/ Composition

Contains neurons: specialized nervous cells, Nervous System

Contain Neuroglia, Nine times more in number than neurons, Support and nourish neutrons

Picture

Epithelial Tissue a.k.a Epithelium

Function

Mainly for protection, External: from injury, drying out, pathogen invasion, Internal: secrets mucus along digestive tract and sweeps up impurities from the lungs

Also for secretion, absorption, excretion, and filtration

Found

Covers body surfaces and lines boy cavities

In the lining of the lungs, blood vessels, kidney tubules, digestive tracts, and oviducts

Types

Squamous epithelium

Cubodial epithelium

Columnar epithelium

Appearance/ Composition

Occur in more than one layer

Named according to the shape of the cell

Cells lining a body cavity can be ciliated and/or grandular

Tightly packed cells that form a continous layer
