c) How does one nerve cell communicate with another? - Nerve cells communicate with one another through neurotransmitters. 2. a) Explain what neurotransmitters are? - Neurotransmitters are chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing where that neuron will generate a neural impulse.
The communication takes place through electrical impulses and chemical reactions produced and received by specialized cells called neurons, which use axons to deliver these messages. However, the brain is not just a single piece. It has two hemispheres united by a thick group of axons called corpus callosum. We would think that it acts like any other organ, but the reality is that each hemisphere has specific abilities and functions. For example: the right hemisphere controls the left side of the body, and the right hemisphere controls the left side.
3. Return to the main Endocrine System homepage and click on the Pituitary Gland. a. The pituitary produces several hormones that regulate various parts including other endocrine glands. This rather large role earns it the “master gland” nickname.
Clear intro to topic and essay Q The nervous system is the body’s internal electrochemical communications network. Its main parts are the brain, spinal cord and the nerves. The brain and the spinal cord form the central nervous system, which is the body’s chief controlling and coordinating centre and billions of long neurones, many grouped as nerves, make up the peripheral nervous system, transmitting nerve impulses between the central nervous system and other regions of the body. Each neuron has three parts, a cell body, branching dendrites that receive chemical signals from other neurons and a tube-like axon that conveys these signals as electrical impulses. There are two types of neurons: sensory neurons and motor neurons.
What are the components of the ANS (long) neural reflexes? The components of the ANS (long) neural reflexes include a CNS control center in the spinal cord and the brain. b. What is the stimulus for ANS regulation? Distention for many involuntary digestive movements.
Correct The structure that separates the left and right cerebral hemispheres is the: Your Answer: Longitudinal fissure. 2. Correct The lobe of the brain involved with the coordination of autonomic functions is the: Your Answer: Insula. 3. Correct The structure of the brain that regulates the endocrine system is the: Your Answer: Hypothalamus.
The Cerebrum is located in the upper most part of the brain and divided into left and right hemispheres which are divided again into four different lobes. Its functions actually give us the ability to read, speak, write, calculate, compose music, remember, plan, motor function, perceiving and touch sensation. This section of the brain has proved to be the most developed and as well as the largest part of the brain. (Pages 428- 430) 4. White matter is made up of myelinated axons; the white of myelin is where White matter actually gets its name from.
The human brain can be considered the most complex organ in the human body and also the centrepiece of the nervous system. Although the brain works as a unified whole, neuroscientists can identify areas within it that perform specific functions. Your brain is organized into three interconnected layers: the central core, limbic system and the cerebral cortex, all of which contain structures that regulate everyday life. (The Human Brain, Discovering Psychology) The central core is found in all vertebrates. Its five main regions help regulate basic life processes, including breathing, pulse, arousal, movement, balance and sleep and the early stage of processing sensory information.
The frontal lobe regulates movement and handles language production. The parietal lobe deals with sensations. These two halves communicate by means of a bundle of axons Importance in the Brain 2 called, the corpus callous, and each side of the brain controls the opposite side of the body. See, two is better than one. The largest and most important section or Lobe is the Frontal which involves voluntary movement, thinking, personality, and intentionality or purpose.
Ipso-facto human brain is the primary source of human behavior. Under this broad domain of human behavior, speech perception is a part. The whole process of speech perception involves many complex aspects and this paper is partly an attempt to understand speech perception in terms of its physiological and psychological attributes. The hearing process is controlled by human ear which is also a complex organ; the auditory information captured by the human ear is delivered
