Illustration of human nervous reflex arc Featured 10 Oct 2002 Print

Illustration of human nervous reflex arc

Illustration depicting the human nervous reflex arc, showing the components involved in the muscular response of the arm to the stimulation caused by the heat of a candle flame against the hand. The pain impulse passes via a sensory nerve from the hand to synapses (junctions) in the white matter of the spinal cord (top right) which connect with two motor nerves that supply the biceps (right) and triceps muscles in the upper arm. Thus the sensation of pain caused by the heat of the flame provokes an upward jerk of the hand

Pollinated flower pistil, SEM Featured 10 Oct 2002 Print

Pollinated flower pistil, SEM

Pollinated flower pistil. Coloured scanning electron micrograph (SEM) of pollen (round, orange) on the stigmas (yellow) of a field pennycress (Thlaspi arvense) flower pistil. The pistil is the female reproductive part of the flower. It can be divided into several carpels with a stigma at their tips. The stigma is where pollen lands during pollination. The pollen grains are male gametes (reproductive cells) that can fertilise a female gamete to produce a seed. This requires the male gamete to travel down the style (the structure that supports the stigma) to the ovary at the base of the pistil. Magnification: x33 at 6x7cm size
