They do this by either synapsing directly to lower motor neurons‚ or by synapsing with a local circuit neuron‚ which then synapses with a lower motor neuron. The upper motor neurons originate in the motor region of the cerebral cortex or brainstem. The neurons from the cerebral cortex are important for planning‚ initiating‚ and directing voluntary movements. Neurons from the brainstem help to regulate muscle tone‚ control postural muscles‚ and help maintain balance and orientation of the head and body

Summary of Module 31 Functions of emotions : * Preparing us for action. Emotions act as a link between events in our environment and our responses. * Shaping our future behavior. Emotions promote learning that will help us make appropriate responses in the future. * Helping us interact more efficiently with others. We ooften communicate the emotion we experience through our verbal and nonverbal behaviors‚ making our emotions obvious to observers. Determining the Range of Emotions:

able and see a change in an image. The ganglion cells then use this information to send an output through the optic nerve and into the brain. The function of the optic nerve is to transfer information through the thalamus and into the cerebral cortex. The cerebral cortex is where the process of visual perception is located. The optic nerve also transfers information that is used for the important mechanics of vision. These mechanics are in two different places in the brain stem. The first site is the

For holistic development we mean to the human development that is involve all the part of a person and it’s designed to accommodate all the area of development of a child. Such as communication and language‚ physical development and personal‚ social and emotional development. Holistic education try to teach to children using a natural and fun method instead of compartmentalizing development areas. To understand why the holistic development is important we need to remember that even if we consider

Psychology is the study of behavior and mental processes‚ this includes peoples thoughts‚ emotions‚ perceptions‚ memories‚ reasoning‚ and biological activities. Define the cerebral cortex The layer of unmyelinated neurons (gray matter) forming the cortex of the cerebrum. The cerebral cortex is responsible for higher functions of the nervous system‚ including voluntary muscle activity and learning‚ language‚ and memory. It is composed of neurons and axons. Define

spinal cord. Both the brain and spinal cord are protected by three layers of connective tissue called the meninges. Within the central nervous system is a system of hollow cavities called ventricles. The network of linked cavities in the brain (cerebral ventricles) is continuous with the central canal of the spinal cord. The ventricles are filled with cerebrospinal fluid which is produced by specializedepithelium located within the ventricles called the choroid plexus. Cerebrospinal fluid surrounds

cells that detect sensory information. The sensory receptors then initiate neural impulses. Sensation occurs when the neural impulses arrive at the cerebral cortex. Neural impulses that begin in the optic nerve are sent to the visual areas of the cerebral cortex‚ and we see objects. Each person’s unique perception results from how the cerebral cortex interprets the meaning of the sensory information. Sensory adaptation: brain filters out redundant‚ insignificant information.
