Transmission electron micrograph showing an over view of muscle tissue configuration from a mouse cardiac muscle ventricle. This image shows muscle to muscle connection and the abundance of mitochond...

Transmission electron micrograph of a highly magnified and cropped image of a capillary in a mouse cardiac muscle. The capillary is used mainly for the transport of nutrients and oxygen through the e...

Rough endoplasmic reticulum and Golgi in the epidermal cell of Fundulus heteroclitus scale. Endoplasmic reticulum studded with protein-manufacturing ribosomes form a continuous network along the perip...

Transmission electron micrograph of four longitudinally cut ventricle muscle fibers of mouse cardiac tissue. Muscle fibers are multinucleate celsl composed of myofibrils that contract when stimulated...

Transmission electron micrograph of a blood vessel in the atria of a mouse cardiac tissue. This image is a close up of a red blood cell in a blood vessel.

Transmission electron micrograph of coated vesicles in mouse cardiac tissue. Coated vesicles have the materials bound to the receptor molecules incorporated within their membranes allowing the vesicl...

Transmission electron micrograph of intercalated disks with a desmosome from the atria of mouse cardiac muscle cells. The intercalated disks are where the junction of two opposing membranes of adjace...

Low magnification of the epidermal region of the Fundulus heteroclitus scale. The epidermis is separated from the collagen layers of the dermis by the basement membrane. The cells of the epidermis (to...

Transmission electron micrograph of ventricle tissue of a mouse cardiac muscle. This image shows the various areas of a muscle fiber. The Z lines are the very dark borders that link sarcomeres. Th...
