Skeletal muscle with striations

Simple squamous epithelium (layer at very top of tissue)

Simple ciliated columnar epithelium (upper respiratory tract, uterine ducts …)

Sickle cell anaemia red blood cell sample

Reticular tissue – network of support fibres for lymphatic system, found in lymph nodes, spleen, thymus and bone marrow.

Psuedo-stratified columnar epithelium (fluorescent).

Multipolar neurons (one axon, many dendrites)

Mammal motor nerve cells (yellow fluorescent imaging)

Intact smooth muscle.

Hyaline cartilage

Human adipose tissue

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 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.

Cooleys (Thalassemia) anaemic blood.  Note the clear blood cells.  A genetic disorder, the body makes an abnormal form of hemoglobin.

Compact bone

Ciliated columnar epithelium

Chronic lymphocytic leukemia

Cardiac muscle

Cancellous (spongy) bone

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.
