Topographical Basis of Tissue Organisation

It conducts electrical impulses

It conducts thermal energy in thermoregulation

It transports nerves and blood vessels to the epidermis

It controls the secretion of sweat from the sweat glands

Allows independent contraction and reduces friction between different muscles

Provides pathway for nerves and blood vessels to the muscles

Secretes Ca2+ into the sarcoplasm for contraction

The muscles have different embryological origins

A double membrane between which fluid is found

The deep fascia sheath surrounding a muscle

An embryological membrane (such as the anal membrane) which must be perforated during life

The deep fascia layer surrounding an organ (e.g. the kidney)

Mesothelium

Endothelium

Epithelium

Mesenchyme

Minimises friction to allow movement of smooth muscle without damage to organs

Provides pathway for nerves and blood vessels to the organs

Provides large surface area for the absorption of waste materials from the organs

Supplies the organs with nutrients

Collateral arteries

Anastomoses

Plexus arteries

Synovial arteries

Superficial veins are potentially visible through the skin whereas deep veins are surrounded by muscle

Superficial veins occur at the skin whereas deep veins are surrounded by connective tissue

Deep veins only occur around organs whereas superficial veins occur anywhere else

Deep veins has thicker walls and smaller lumens than superficial veins

Valves

Anastomoses

Collateral veins

Elastic walls
