Fibrous (dense) connective tissue tissue – notice the wavy pattern of the collagen.  Tendons and ligaments.

Elastic tissue – found on the wall of the aorta, for example, to provide recoil.  Also found in other arteries and in the lungs.

elastic tissue

Elastic cartilage – contains elastic fibres instead of collagen.  Found in external ear, auditory tubes and the larynx.

Cuboidal epithelium – single layer of cells.  Found lining nephrons of the kidneys.   Also found in glandular ducts, ovaries, thyroid gland and repiratory bronchioles.

Brown adipose tissue – each cell contains small lipid droplets and a high number of iron containing mitochondria.  Generates heat by burning calories.  Newborns do not shiver with cold because they have their brown adipose tissue levels are higher than adults.
