are cerebral cortex of the brain and nervous system
The hindbrain is made of the cerebellum, pons and medulla. Often the midbrain, pons, and medulla are referred to together as the brainstem. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action.The cerebral cortex is divided into four sections, called lobes: the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.he hindbrain is made of the cerebellum, pons and medulla. Often the midbrain, pons, and medulla are referred to together as the brainstem. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The human nervous system is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS, in turn, is divided into the brain and the spinal cord, which lie in the cranial cavity of the skull and the vertebral canal, respectively.he spinal cord is an essential link between the peripheral nervous system and the brain; it conveys sensory information originating from different external and internal sites via 31 pairs of spinal nerves (Figure 1.5). The cerebral cortex is the cerebrum 's (brain) outer layer of neural tissue in humans and other mammals.It is divided into two cortices, along the sagittal plane: the left and right cerebral hemispheres divided by the medial longitudinal fissure.he cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries. It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves. Together they control every part of your daily life, from breathing and blinking to helping you memorize facts for a test.he hindbrain is made of the cerebellum, pons and medulla.

The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. Central Nervous System. The central nervous system is divided into two parts: the brain and the spinal cord. The average adult human brain weighs 1.3 to 1.4 kg (approximately 3 pounds).The brain contains about 100 billion nerve cells (neurons) and trillions of support cells called glia.entral Nervous System. The central nervous system is divided into two parts: the brain and the spinal cord. The average adult human brain weighs 1.3 to 1.4 kg (approximately 3 pounds). The Brain and Cerebrum. The cerebrum is the largest part of the brain and controls voluntary actions, speech, senses, thought, and memory. The surface of the cerebral cortex has grooves or infoldings (called sulci), the largest of which are termed fissures.Some fissures separate lobes.he cells in the gray matter extend their projections, called axons, to other areas of the brain. Fibers that leave the cortex to conduct impulses toward other areas are termed efferent fibers, and fibers that approach the cortex from other areas of the nervous system are termed afferent (nerves or pathways). The cerebral cortex plays a key role in memory, attention, perception, awareness, thought, language, and consciousness. The human cerebral cortex is 2 to 4 millimetres (0.079 to 0.157 in) thick. In large mammals, the cerebral cortex is folded, giving a much greater surface area in the confined volume of the skull.he cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries. It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons. The Brain and Nervous System. The nervous system is broken down into two major systems: Central Nervous System and Peripheral Nervous System. We’ll discuss the Central Nervous System first. The Central Nervous System consists of the brain and the spinal cord.The Cerebral Cortex, which is involved in a variety of higher cognitive, emotional, sensory, and motor functions is more developed in humans than any other animal.he nervous system is broken down into two major systems: Central Nervous System and Peripheral Nervous System. We’ll discuss the Central Nervous System first. The Central Nervous System consists of the brain and the spinal cord. Figure 1.6. The central nervous system, which includes the spinal cord and the brain, is the most protected organ in the human body. It is protected from the external environment by three barriers: skull, meninges, and cerebral spinal fluid (CSF).he spinal cord is an essential link between the peripheral nervous system and the brain; it conveys sensory information originating from different external and internal sites via 31 pairs of spinal nerves (Figure 1.5). The cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.It contrasts with the underlying white matter, consisting mainly of the white myelinated sheaths of neuronal axons.he cerebral cortex is gray matter, consisting mainly of cell bodies (with astrocytes being the most abundant cell type in the cortex as well as the human brain as a whole) and capillaries.
