The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric. The autonomic nervous Read More …

Hearing – Anatomy, Structure, Functions
Hearing allows one to identify and recognize objects in the world based on the sound they produce, and hearing makes communication using sound possible. Sound is derived from objects that vibrate producing pressure variations in a sound-transmitting medium, such as air. Read More …
Taste – Anatomy, Structure, Functions
Taste is the sensory system that is partially responsible for the perception of taste (flavor).[1] Taste is the perception produced or stimulated when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with olfaction and trigeminal nerve stimulation (registering texture, pain, and temperature), Read More …
Pain Sensation – Anatomy, Types, What About You Need To Know
Pain Sensation/Pain is a general term that describes uncomfortable sensations in the body. It stems from the activation of the nervous system. Pain can range from annoying to debilitating. It may feel like a sharp stab or dull ache. It may also Read More …
Reflex Arc – Anatomy, Types, Functions
A reflex arc is a neural pathway that controls a reflex. Invertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain. The brain will Read More …
Sensory and Motor Pathways – Anatomy, Types, Functions
Sensory and Motor Pathways/Generally, spinal nerves contain afferent axons from sensory receptors in the periphery, such as from the skin, mixed with efferent axons traveling to the muscles or other effector organs. As the spinal nerve nears the spinal cord, Read More …
The Descending Tracts – Anatomy, Types, Structure, Functions
The descending tracts are the pathways by which motor signals are sent from the brain to lower motor neurones. The lower motor neurones then directly innervate muscles to produce movement. The motor tracts can be functionally divided into two major groups: Pyramidal Read More …
Motor Pathways – Anatomy, Types, Structure, Functions
Motor pathways carry signals from the brain to skeletal muscle and smooth muscle such as those contained in glands. The system consists of upper and lower motor neurons. The information provided below is primarily focused on the motor pathways that coordinate skeletal muscle movement, i.e. motor pathways Read More …
How to Help Your Child Develop Fine Motor Skills
Fine motor skills refer to the coordination between your child’s small muscles, like those in their hands, wrists, and fingers in coordination with their eyes. Fine motor skills involve the small muscles of the body that enable such functions as writing, grasping small objects, and fastening clothing. Early childhood development includes Read More …
What Are Gross Motor Skills? – What You Need To Know
Gross motor skills are the abilities usually acquired during childhood as part of a child’s motor learning. By the time they reach two years of age, almost all children are able to stand up, walk and run, walk upstairs, etc. These skills are built upon, Read More …
Gross Motor Skill – Anatomy, Types, Structure, Functions
Gross motor (physical) skills are those which require whole-body movement and which involve the large (core stabilizing) muscles of the body to perform everyday functions, such as standing, walking, running, and sitting upright. It also includes eye-hand coordination skills such Read More …
