the central nervous system objective to learn about the central nervous system [Music] the nervous system is responsible for sending receiving and interpreting information from all parts of the body it responds to external stimuli and also monitors and coordinates the functions of internal organs the central nervous system is composed of the brain and spinal cord both are enclosed in protective layers called meninges the outer layer is called the dura mater the middle layer is called the arachnoid mater and the inner layer is called the PIA mater the subarachnoid space or the space between the arachnoid and the PIA mater is filled with cerebrospinal fluid the brain the brain is located in the cranium of the skull it is made of three main parts the cerebrum cerebellum and medulla oblongata the cerebrum is the largest part of the brain and is divided into left and right hemispheres each is composed of a frontal temporal parietal and occipital lobe the two hemispheres are connected by a nerve tract called the corpus callosum [Music] the surface of the cerebral hemisphere is folded which increases the surface area the cerebrum is concerned with learning memory interpretation and personality the cerebellum is located in the back of the brain just below the cerebrum it controls balanced movement and coordination the brain stem is located beneath the cerebrum and in front of the cerebellum it connects the brain with the spinal cord and is composed of the midbrain pons and medulla oblongata the brain stem controls a number of autonomic functions including respiration and blood pressure the spinal cord the spinal cord extends from the medulla oblongata and down the back it is protected by the vertebral column the spinal cord is a hollow tube containing cerebrospinal fluid 31 pairs of spinal nerves arise from the spinal cord these nerves transmit information from body organs to the brain and from the brain to the organs summary the brain and the spinal cord comprise of the central nervous system the brain is located in the cranium the spinal cord is located in the vertebral column
