Flys eye

Fly's eye. Coloured scanning electron micrograph (SEM) of a fly's (order Diptera) compound eye. The eye is made up of numerous visual units, known as ommatidia. Each ommatidium consists of an outer cuticle covering a lens, beneath which is a group of light-sensitive cells known as the retinula. Nerve fibres from the retinula converge onto the optic nerve, relaying visual signals to the brain. The image seen by a fly is thought to be a mosaic image, poorly focused but good at detecting movements

Nose, mouth and throat

Nose, mouth and throat. Cutaway artwork of the anatomy of the nose, mouth and throat. The large nasal cavity (upper centre) is lined with nerves (yellow) branching from the olfactory bulb (above) that leads back to the brain. At the back of the nasal cavity, and also at left of the eye, are two of the facial sinuses (spaces in the bone). In the mouth, teeth are seen embedded in the jaw bones. The roof of the mouth is both bone and soft tissue (the soft palate). When closed, most of the mouth is filled with the tongue. The nose and mouth lead into the pharynx, which splits into the oesophagus (rear) and trachea (front). The top of the trachea is the larynx (voicebox, hole at lower right)
