Question 1 Skeletal System The skeletal system is a strong yet light‚ flexible living framework that supports the body‚ protects delicate internal organs and makes movement possible. In addition‚ our bones store minerals while red bone marrow produces blood cells. Support The skeleton provides a frame that shapes the body and holds it up. Within the skeleton different characteristics of support can be identified. As the body’s main axis‚ the backbone provides support to the trunk with its upper

inner ear consists of the spiral-shaped cochlea (an ancient Greek word for the shell of a snail). The passageways of the cochlea are lined with about 20‚ 000 microscopic hair cells that convert sound vibrations into nerve impulses which are then sent to the brain. Here‚ these impulses are interpreted as meaningful sounds. There are only 15‚000 hair cells to perform this analysis‚ and they pass the information to the auditory

cones. Cones are any of the cone shaped receptors in the retina that respond to color. Rods are the long shaped receptors that respond to faint light. The eye perceives optic illusions because of blind spots in the eye that are due to where the optic nerve enters the eye and is lacking rods and cones. This area is insensitive to light; the brain will often assume what is there and fills it in with what makes sense. 10. How does an error in the structure or function of the eye relate to disease or

Nodes of Ranvier: a gap between two of the Schwann cells that make up an axon’s myelin sheath; serves as a point for generating a nerve impulse. Resting potential: the difference in electrical charge across the plasma membrane of a neuron. Sodium-potassium pump: the mechanism that uses ATP energy to reset the sodium and potassium ions after transmission of a nerve impulse. Active transport: transport of molecules against a concentration gradient with the aid of proteins in the cell membrane and energy

BRAINPORT VISION DEVICE By D.KALAIVANI R.PARVATHI DEVI ABSTRACT “BRAINPORT DEVICE” The device which sends visual input through tongue in much the same way that seeing individuals receive visual input through the eyes is called the “Brainport Vision Device”. BrainPort could provide vision-impaired people with limited forms of sight. To produce tactile vision‚ BrainPort uses a camera to capture visual data. The optical information

Hypertension is a common health problem especially among people over age of 60 years. This disease is diagnostic when a patient blood pressure is more than 140 to 159 over 90 to 99. Blood pressure refers to the pressure that blood applies to the inner walls of the Diabetes is an endocrine system disorder that occurs when the body is unable to control or balance the amount of sugar in blood and within bodily tissues.
