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 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 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...

Painting of Neuron From Cortex Of Brain

Painting of Gray Matter:It is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and both unmyelinated axons and myelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries. Grey matter contains neural cell bodies, in...

Painting of Brainstem ventral view:The most medial part of the medulla is the anterior median fissure. Moving laterally on each side are the pyramids. The pyramids contain the fibers of the corticospinal tract (also called the pyramidal tract), or the upper motor neuronal axons as they head...

Painting of Cortex:The cerebral cortex is a structure within the brain that plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness. It constitutes the outermost layer of the cerebrum. In preserved brains, it has a grey color, hence the name "grey...

Vector Generated Image of Sensory nerves

Painting of Amyotrophy:Amyotrophy is progressive wasting of muscle tissues. Muscle pain is also a symptom. It can occur in middle age males with type 2 diabetes. It also occurs with Motor Neuron Disease.

Vector Generated Image of Nervous system in arthropods consists of ganglia :The central nervous system consists of a series of ganglia that supply nerves to successive segments of the body. The three main ganglia in the head (protocerebrum, deutocerebrum, and tritocerebrum) commonly are fused to...

Vector Generated Image of Motor nerves allow the brain to stimulate muscle contraction. A motor nerve is an efferent nerve that exclusively contains the axons of somatic and branchial motoneurons, which innervate skeletal muscles (that ensure locomotion) and branchial muscles (that motorize the...

Painting of Photo receptor cells in human eye rods & cones:A Photo receptor, or Photo receptor cell, is a specialized type of neuron (nerve cell) found in the eye's retina that is capable of phototransduction. The great biological importance of Photo receptors is that as cells they...

Painting of Neuroglial cells:Glial cells, commonly called neuroglia or simply glia (Greek for "glue"), are non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system. In the human brain, there is...

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...
