Painting of Sphenodon guntheri,The Brothers Island tuatara is one of the oldest animals in the world today . It may look like a lizard but it belongs to the order Rhynchocephalia, which includes ancient reptiles that existed 200 million years ago. All other species in this order, apart from the...

Painting of Neural tissue:Nervous tissue is the main component of the nervous system-the brain, spinal cord, and nerves-which regulates and controls body functions. It is composed of neurons, which transmit impulses, and the neuroglia, which assist propagation of the nerve impulse as well as...

Painting of Nerve:A nerve is an enclosed, cable-like bundle of peripheral axons (the long, slender projections of neurons). A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons. Nerves are found only in the peripheral nervous...

Painting of Hyaline cartilage:Hyaline cartilage (aka “Gristle") consists of a slimy mass of a firm consistency, but of considerable elasticity and pearly bluish color. It contains no nerves or blood vessels, and its structure is relatively simple. Except where it coats the skin and the...

Painting of Frontal view of Eye:Eyes are organs that detect light, and send electrical impulses along the optic nerve to the visual and other areas of the brain.

Painting of Synapses:Synapses are functional connections between neurons, or between neurons and other types of cells.Synapses are generally too small to be recognizable using a light microscope except as points where the membranes of two cells appear to touch, but their cellular elements can be...

Painting of Neurons:is an excitable cell in the nervous system that processes and transmits information by electrochemical signaling. Neurons are the core components of the brain, the vertebrate spinal cord, the invertebrate ventral nerve cord, and the peripheral nerves. A number of specialized...

Painting of Autonomic Nervous System Lower Half

Painting of Autonomic Nervous System Upper Half

Painting of Numeromodulator:A neuromodulator is a relatively new concept in the field, and it can be conceptualized as a neurotransmitter that is not reabsorbed by the pre-synaptic neuron or broken down into a metabolite. Such neuromodulators end up spending a significant amount of time in the...

Painting of Neuron From Spinal Chord:The spinal cord extends through hollow openings in each vertebra in your back. It contains various nerve cell bodies (gray matter) and nerve processes or axons (white matter) that run to and from the brain and outward to the body. The peripheral nerves enter...

Painting of Neuron from Retina of Eye:The retina is a complex, layered structure with several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells. These are mainly of two types: the rods and cones. Rods function mainly in...
