Human Physiology

Introduction Neural control and coordination is a crucial aspect of human physiology. Neural system is a well-organised network of point-to-point connections in the human body that allows for speedy coordination, while the endocrine system is responsible for chemical integration via hormones. Coordination refers to the process by which two or more organs interact and complement […]

Introduction The nervous system is a complex network of nerves and cells that transmits signals to and from the brain. In humans, the nervous system comprises two parts: the central nervous system (CNS) and the peripheral nervous system (PNS).  The CNS consists of the brain and spinal cord, while the PNS includes all other nerves

Introduction The functioning of the human body completely depends upon the nervous system. The nervous system gives us the sense of taste, watching, hearing, feeling, etc. The human nervous system is the system that conducts development and improvements from the sensory receptors. The receptor comes from the brain and spinal cord and leads your impulses

Introduction The conditions of our body are controlled in two ways with chemical and nervous responses. Cells known as the receptors  help to detect the stimuli (i.e. any changes in the environment). The coordination centre, like the brain, spinal cord or pancreas, that receives and processes information from the receptors around the whole body. Our

Electrical impulses are used by the nervous system to gather, process, and respond to information about the environment. Neurons are used for receiving and sending electrical impulses among the body due to their unique structure. Glial cells, which surround, shield, and insulate neurons, provide support. The endocrine system, like the nervous system, also acts like

Introduction  A nerve can be defined as the cable-like structure that forms a nervous system in the human body. It is one of the vital yet complex domains as they are responsible for sending messages and coordinating with different body parts. Hence, it can be said that nerves are critical to healthy living.  Nerve  A

Introduction It is the electric signals that travel down the dendrites in order to form a nerve impulse or an action potential that are known as nerve impulses. When ions flow into and out of the cell, this results in the generation of an action potential. It is specifically associated with the ions sodium and

Gated channel protein is an essential concept in the field of neuroscience. These are referred to as a class of transfer proteins signifying a gate opening that lets a molecule pass through the membrane.  These proteins have specific functions for the given molecule or ion in response to external stimuli causing the gate to open

The pons is often referred to as the pons Varolii (“bridge of Varolius”), in honour of the Italian anatomist and surgeon Costanzo Varolio (1543–75), who designed the bridge in the first place.  Among the neuronal routes and tracts in this part of the brainstem are those that channel signals from the brain down to the

The pupil is a little black circle in the iris’s middle. It’s a little hole above the lens through which light enters the eye and concentrates on the retina to generate an image. Iris muscles control the size of the pupil and the amount of light that enters it. The pupil is the centre entrance
