Adrenal gland in cross section, endocrine gland. This medical illustration shows the structure of the adrenal gland in a frontal cut. We can see the adrenal medulla in the center in purple. This structure secretes norepinephrine and adrenaline (increased heart rate and increased blood pressure). Around the adrenal medulla is the adrenal cortex. This is the adrenal cortex part. It produces hormones called corticosteroids (Cortisol), mineralocorticoids (Aldosterone), and androgens. (Photo by: JACOPIN/BSIP/UIG)

Illustration of the path of sound in the ear. The sound wave captured by the ear's auricle penetrates into the auditory canal, vibrates the tympanic membrane which in turn vibrates the ossicles (hammer, anvil, stirrup). The stirrup's vibrations cause movement in the oval window's membrane which produce hydraulic waves in the cochlea's perilymph, putting pressure on the endolymph within the cochlear duct, displacing the basilar membrane, pushing the stereocilia against the tectorial membrane and producing nervous impulses in the cochlear's nervous fibers. This nervous impulse progresses in the auditory nerve, then from neuron to neuron through the bone marrow until it reaches the auditory cortex in the brain which analyses the data.

Motor neuron, final pathways of the motor pathway system, innervation of muscle fibers. Motor neurons are cells that control the movement of the body. The motor neuron is also called a motor neuron. it is represented in purple. The motor neuron ends in a kind of button or synapse, connected to muscle fibers. This connection is made at an area called the neuromuscular junction. This type of neuron is a nerve cell allowing all movement control. It is present in the spinal cord. It controls the muscles through the peripheral nerve. (Photo by: JACOPIN/BSIP/UIG)

Nephron, structural and functional unit of the kidney, formation of urine. The nephron is made up of a renal corpuscle, the glomerulus, and a tubular system. The glomerulus, located in the renal cortex, contains a cluster of capillaries. It produces the primary urine by filtering the blood. The uriniferous tube passes through the cortex and the medulla. It makes the final urine from the primary urine. It is subdivided into 4 segments: the proximal convoluted tube, which follows the glomerulus, the loop of Henle, the distal convoluted tube then the collecting tube (or canal). The latter opens at the bottom of the small calyces (ducts flowing into the large calyxes, which discharge urine into the pelvis) in an area called the renal papilla. Each of these segments has a precise physiological function, which involves both reabsorption phenomena (recovery of part of the water, sodium, etc.). But it also involves secretion phenomena, to transform the primary urine, formed in the glomerulus,

Cross-section illustration of transmission of visual information. The transmission of visual information takes place from the retina, via the optic nerve and to the visual cortex. Some information crosses the brains horizontal axis (decussation) at the optic chiasma, while other information is unilateral. All the visual information then arrives at the left and right lateral geniculate bodies, cerebral relays which transmit visual information to other neurons. These then transmit the information to the primary, left and right visual cortexes.

Illustration of spinal stenosis in L4 and L5. Spinal stenosis is a pathology located in the lumbar spinal column where the cauda equina nerves pass. It is caused by an intrinsically narrow vertebral canal or a degenerative narrow canal related to a herniated disc, an increase in the volume of rear joints and ligaments that join the vertebrae together, or an instability in the vertebrae with vertebral displacement (or degenerative spondylolisthesis), which decreases the diameter of the canal, compressing the nerves, causing lumbar pain in the lower limbs.

Muscle structure, skeletal muscle, muscle bundle and fiber. The muscle is attached to the bone by the tendon. It is covered by the deep fascia. Several muscle bundles make up muscle. A first membrane called epimysium covers these bundles. But each bundle is also covered by a membrane called the perimysium. They are also made up of a number of muscle fibers covered with endomysium. Myofibrins are the last units of muscle structure. They are not isolated in this drawing. But they are represented by the pinkish beige dots on the section of the muscle fiber. (Photo by: JACOPIN/BSIP/UIG)

The zoom on the left of the illustration represents the macula and the retinal cells composed only of cones concentrated in the area of the fovea. Outside the fovea, the retinal cells are composed of cones and rods.

The path of sound in the ear. Representation of the path of sound in the ear. The sound wave picked up by the pinna of the ear penetrates the auditory canal, vibrates the eardrum which vibrates the ossicles (hammer, anvil, stirrup). The vibrations of the stapes vibrate the membrane of the oval window which generates hydraulic waves in the perilymph of the cochlea, which exerts pressures of the endolymph inside the cochlear canal, displacing the basilar membrane, dragging the cells cilia that move against the tectorial membrane producing nerve impulses in the cochlear nerve fibers. This nerve impulse travels through the auditory nerve, then from neuron to neuron via the spinal cord to the auditory area of the brain which analyzes the data.

The lumbar disc herniation (contents of the nucleus of the vertebral disc that protrudes behind the vertebra in the vertebral canal and compresses the root of the nerve, causing inflammation) represents 90% of the causes of sciatica. In this illustration the hernia on the left is represented on a superior view of a lumbar vertebra. On the right, it is represented on a median sagittal section of the lumbar spine and the beginning of the sacred column .
