The Brain / Psy 240 / Week Two The human brain is one of the most complex and fascinating parts of the body. The major regions of the brain are separated into three layers called the central core‚ the limbic system‚ and the cerebral hemispheres or otherwise called the forebrain‚ midbrain‚ and hindbrain. The forebrain houses the cerebrum‚ thalamus‚ and hypothalamus. The midbrain houses tectum and tegmentum. The hindbrain houses the cerebellum‚ pons‚ and medulla. From here the brain is divided

meaning it looks like a little net. It is made up of about 100 tiny nuclei that occupies the central core of the brainstem. Parts of the myelencephalon play a part in arousal. The functions of the myelencephalon include sleep‚ attention‚ and movement‚ the maintenance of muscle tone and various cardiac‚ circulatory and respiratory reflexes. According to this collection of nuclei‚ it is an activating system and this means that it can be misleading to us. Metencephalon is also made up of many ascending

Chapter 14 Vocabulary: The Autonomic Nervous System 1. Autonomic Nervous System - Consists of motor neurons that innervate smooth and cardiac muscle‚ and glands; make adjustments to ensure optimal support for body activities; operate via subconscious control; also called the involuntary nervous system or general visceral motor system. 2. Preganglionic Neuron – First neuron that resides in the brain or spinal cord. 3. Preganglionic Axon – Synapses with the second motor neuron; thin

neurotransmitter with their receptors cause’s vasoconstriction and beta adrenergic receptors increases the heart rate and show vasodilation. (Davidyan‚ 2017) The parasympathetic nervous system decreases the blood pressure as well as heart rate through vagus nerve. The diameter of the blood vessels is regulated by the vasomotor system. Vasomotor nerves made up of sympathetic motor nerves transmit impulses to the vasomotor center to innervate smooth muscles in arteries which maintain a vasomotor tone to bring

Accommodations involve a wide range of techniques and support systems that help students with disabilities work around any limitations that result from their disability (Rowley & Reigel 1993). There are five accommodations for students with Spina bifida‚ instructional methods and materials‚ assignment’s and classroom assessments‚ time demands and scheduling‚ learning environment‚ and use of physical communication systems. Not every child with Spina bifida will need accommodations for school

Hydrocephalus is commonly referred to as "water on the brain." The so-called "water" is actually cerebrospinal fluid (CSF)‚ a clear liquid that looks like water and is produced in the 4 ventricles (cavities) of the brain‚ connected by narrow pathways‚ leading to an increase in intracranial pressure (ICP) [2]. This condition is likely to be fatal if not treated. Fitting of a ventricular shunt diverts the excess fluid from the brain to the thoracic cavity and is a very effective treatment for hydrocephalus
