Epithelial Tissue

By James

Simple Squamous

• Consists of only

one layer of flat,

scale-like cells.

• Microscopic air

sacs of the lungs,

for example, are

composed of this

kind of tissue.

Stratified Squamous

• Characterized by

multiple layers

of cells with

typical flattened

squamous cells.

Transitional

• Is a stratified tissue typically found in body areas, such as the wall of the urinary bladder, that are subjected to stress and tension changes

Simple Columnar

• Composes the

surface of the

mucous

membrane that

lines the

stomach, uterus,

uterine tubes,

and parts of the

urinary tract

Stratified Columnar

• Has multiple

layers of

columnar cells,

only the most

superficial cells

are truly

columnar in

appearance

Psuedostratified

• Found lining the

air passages of

the respiratory

system and

segments of the

male

reproductive

system such as

the urethra

Simple Cuboidal

• Composed of

one layer of

cuboidal cells

resting on a

basement

membrane

Stratified Cuboidal

• Two or more rows

of low cuboidal

cells are arranged

randomly over a

basement

membrane

Glandular

• Regardless of the secretory product produced, glandular activity depends on complex and highly regulated cellular activities requiring the expenditure of stored energy

Connective Tissue

By Ross

Loose Ordinary Fibrous

• The substance

contains a large

proportion of ground

substances and lacks

the massive fibrous

reinforcement.

Adipose

• Adipose is a major

storage site for fat in

the form of

triglycerides.

Reticular

• Forms the basis of such

hematopoietic organs.

Dense Regular Fibrous

• Contains densely

packed collagen fibers

that run in the same

direction.

Dense Irregular Fibrous

• Contains fibers that

are not parallel to

each other.

Bone Tissue

• Tight and packed

closely together.

Compact to hold

form and structure.

Hyaline Cartilage

• Is pearly bluish,

consistent, and

considerable

collagen.

Fibrocartilage

• Helps with flexibility

and toughness to

maintain structure

and form.

Elastic Cartilage

• Contains fiber

networks and

collagen fibers.

Blood

• Carries oxygen in to

the tissue and takes

out carbon dioxide

to be released from

the body.

Muscle

By Josh

Skeletal

• Skeletal muscles are used to facilitate movement, by applying force to bones and joints; contraction. They generally contract voluntarily, although they can contract involuntarily.

Cardiac

• This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control. However this type of muscle is highly specialised. It is under the control of the autonomic nervous system, however, even without a nervous imputcontractions can occur due to cells called pacemaker cells. Cardiac muscle is highly resistant to fatigue due to the presence of a large number of mitochondria, myoglobin and a good blood supply allowing continuous aerobic metabolism.

Smooth

• Smooth muscles are found in the hollow parts of the body. This would be in places like the stomach, intestines, blood vessels and the bladder. Smooth muscles are arranged in layers with the fibers in each layer running in a different direction. This makes the muscle contract in all directions. A smooth muscle is an involuntary muscle. This means that you cannot consciously control this muscle. These muscles are under the control of autonomic nervous system. This system controls many systems without us being aware of them.

Nervous

By Halen

Nervous Tissue

• Is the 4th basic tissue in the body.

• It is organized into 2 systems, the central nervous system and the peripheral nervous system.

• The peripheral system sends impulses to the central nervous system.

• The basic cell of nervous tissue is the neuron.
