Autism is a spectrum disorder, meaning that autistic individuals possess a varied set of strengths and challenges. The concept of neurodiversity recognizes autism as a natural variation in human brain development rather than a disorder or deficit.| Simply Psychology
The myelin sheath is a lipid-rich, insulating layer that surrounds the axons of many nerve cells. Produced by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, it serves to increase the speed of nerve impulses. The sheath is segmented, with gaps called nodes of Ranvier, which play a crucial role in the rapid transmission of electrical signals along the axon.| Simply Psychology
The ventricular system is a network of fluid-filled cavities within the brain, including the lateral, third, and fourth ventricles, which produce and circulate cerebrospinal fluid (CSF). CSF provides cushioning, nutrients, and waste removal for the brain, helping maintain a stable environment for optimal neural function. Disruptions in the ventricular system can lead to neurological disorders and conditions, emphasizing its crucial role in brain health.| Simply Psychology
The peripheral nervous system (PNS) is critical for connecting the central nervous system (CNS) to the rest of the body. It is essential for bodily functions such as movement, sensation, and autonomic processes.| Simply Psychology
Schwann cells are a special type of cell found in the peripheral nervous system (PNS). They play a key role in helping nerves work efficiently by wrapping around nerve fibers and forming a protective layer called the myelin sheath.| Simply Psychology
Neurotransmitters are chemical messengers that play a vital role in how your brain and body communicate. They affect everything from your mood and memory to your heartbeat and breathing.| Simply Psychology
The Central Nervous System (CNS) consists of the brain and spinal cord. It acts as the body's control center, processing sensory information and directing responses. The CNS coordinates both voluntary activities, like movement, and involuntary ones, such as breathing and heartbeat.| Simply Psychology
A neuron is a nerve cell that processes and transmits information through electrical and chemical signals in the nervous system. Neurons consist of a cell body, dendrites (which receive signals), and an axon (which sends signals). Synaptic connections allow communication between neurons, facilitating the relay of information throughout the body.| Simply Psychology
