Human Physiology

The human eye and brain work together to convert light into colour. Light receptors in the eye send information to the brain, which results in the familiar colour sensations. Colour is not inherent in objects, according to Newton. Rather, an object’s surface reflects some hues while absorbing all others. Only the reflected hues are visible […]

Although the term “motor neuron” brings up visions of a single type of movement-controlling neuron, this is not the reality. Both upper and lower motor neurons are categorized as motor neurons, despite the fact that their origins, synapse locations, pathways, neurotransmitters, and lesion aspects are completely different. Motor neurons (or motoneurons) are a complex set

The nervous system includes the spinal cord, while the skeletal system includes the backbone. The spinal cord is made up of lengthy nerves, whereas the backbone is made up of vertebrates. The spinal cord is located within the backbone.  The human backbone is, on average, larger than the spinal cord. The backbone protects the spinal

The primary distinction between humans’ and animals’ brains is that humans’ brains have remarkable cognitive capacity, which is a crowning achievement of evolution, whereas animals’ brains have comparatively less cognitive capacity. Furthermore, the cerebral cortex of the human brain, which is responsible for the higher cognitive capacity, is disproportionately large, accounting for more than 80%

The central nervous system is made up of the brain and spinal cord. This complex system has an impact on everything we do. It controls the actions we choose to undertake, including walking and talking, as well as the natural functions of our body, like breathing and digesting food. Our senses—seeing, hearing, touching, tasting, and

The animal kingdom can be classified into invertebrates and vertebrates. In the invertebrates, there is no backbone, and open circulation systems often characterize them. This particular group can be further classified into several families, out of which is the arthropod. The organisms belonging to this group have a segmented body, chitinous exoskeleton, open circulation system

Corrosion is a broad term that refers to a variety of interactions between a material and its environment that result in a loss of material qualities. Diffusion controlled growth of oxide layers can be caused by interaction with ambient oxygen. These may act as a passivate, protecting the substance from further oxidation. Aqueous corrosion can

The presence of active and electrical potentials along the conductors causes nerve impulse conduction. The nervous system is a vital part of our bodies that regulates and coordinates all of our functions. The nervous system regulates our bodies by generating and transmitting nerve impulses within the brain. This system collects information about the environment through

What is the Central Nervous System (CNS)? The Central Nervous System is the most significant unit in an organism. It is the ‘centre or the hub’ that initiates information, commands, coordinates and also impacts all activities within the body. This is why it is sometimes called the central processing area of the body. The Central Nervous System

The brain is made up of many diverse elements that work together to form a cohesive whole. It is made up of five components, each of which is a crucial player. Cerebrum Cerebellum Brain Stem Pituitary gland (pituitary gland) Hypothalamus Cerebrum The cerebrum is the largest region of the brain, and it is where we
