Myelin surrounding a nerve axon, TEM
Myelin surrounding a nerve axon, coloured transmission electron micrograph (TEM). The concentric round rings are the sheets of a Schwann cells myelin membrane (brown rings)

Retina, SEM
Retina. Coloured scanning electron micrograph (SEM) of a section through a freeze-fractured retina, showing the light-sensitive rods and cones and their associated neurones

Lens fibre of an eye
Lens fibre from an eye. Coloured scanning electron micrograph (SEM) of the fibre-like cells that form the crystalline lens of the eye

Cornea, SEM
Cornea. Coloured scanning electron micrograph (SEM) of a section through a cornea, the transparent region on the outer surface of the eye. The front of the eye is at top

Skeletal muscle fibre. Coloured scanning electron micrograph (SEM) of skeletal muscle fibre. This type of muscle is striated

Smooth muscle, SEM
Smooth muscle. Coloured scanning electron micrograph of smooth muscle from the trachea (windpipe). Smooth muscle is not under voluntary control, unlike skeletal (striated) muscle

Contracted artery, TEM
Contracted elastic artery. Coloured transmission electron micrograph (TEM) of a section through an artery. Red blood cells (erythrocytes) are seen in the lumen (top centre)

Somatic peripheral nervous system
Peripheral nervous system. Computer artwork of the main nerves of the somatic part of the peripheral nervous system. The peripheral nervous system does not include the brain and spinal cord

Surgical face mask, SEM
Surgical face mask, coloured scanning electron micrograph (SEM). This mask is made of the plant material cellulose, which is biodegradable

Straw particleboard. Piece of particleboard made from wheat straw. Particles of straw are produced by milling bales of waste straw, and then bound by a resin to produce a wood-like building material

Banknote security. Euro banknote in ultraviolet light. This highlights security features intended to prevent fraud. Fluorescent ink and strips glow bright blue and red under ultraviolet light

False-colour SEM of cells from lens of hu

Myelinated nerve fibres, SEM
Myelinated nerve fibres. Coloured scanning electron micrograph (SEM) of a section through a bundle of nerve fibres containing a blood vessel (orange)

Neurovascular bundle, TEM
Neurovascular bundle. Coloured transmission electron micrograph (TEM) of a cross section through a neurovascular bundle (NVB)

Nerve fibre node, TEM
Nerve fibre node. Coloured transmission electron micrograph (TEM) of a cross-section through a nerve fibre (axon) at a node of Ranvier

Nerve fibres, TEM
Nerve fibres. Coloured transmission electron micrograph (TEM) of a section through non- myelinated nerve fibres (blue). The fibres are arranged into bundles surrounded by the cytoplasm of Schwann

Nerve fibres. Coloured scanning electron micrograph (SEM) of parallel myelinated nerve fibres in the spinal cord. Each fibre consists of a nerve cell axon, the output process of a nerve cell

Nerve fibre, SEM
Nerve fibres. Coloured scanning electron micrograph (SEM) of nerve fibres (brown). A group of nerves such as this is known as a fasciculus

Coloured SEM of some nerve fibres
Nerve fibres. Coloured scanning electron micrograph (SEM) of some nerve fibres. A group of nerves such as this is known as a fasciculus

False-colour SEM of a bundle of motor nerve fibres
Nerve fibres. False-colour scanning electron micrograph of a bundle of motor nerve fibres (blue). The bundle as a whole is surrounded by a cylindrical sheath of connective tissue

Ilustration of an oligodendrocyte

Lymph node, SEM
Lymph node. Coloured scanning electron micrograph (SEM) of a freeze fracture section through a lymph node, showing part of the medullary sinus

Blood vessels, light micrograph
Blood vessels. Light micrograph of a section through tissue showing an artery (bottom left) and a vein (top right). Two nerve fibres (dark blue) are also seen

Muscular artery. Light micrograph of a transverse section through a muscular artery. This blood vessel has a thick, muscular wall that enables it to carry blood under pressure

Muscle fibres, SEM
Skeletal muscle fibres. Coloured scanning electron micrograph (SEM) of a freeze-fractured bundle of skeletal (or striated) muscle fibres

Tendon fibres, TEM
Tendon fibres, coloured transmission electron micrograph (TEM). A tendon is made up of parallel bundles of collagen fibres

Skeletal muscle, SEM
Skeletal muscle. Scanning electron micrograph (SEM) of a transverse section through skeletal muscle. The many muscle fibres (red) are seen, along with the elastic sheath (epimysium)
