So, this is the key difference between brain and spinal cord meninges. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. 2. The CSF is present in both, and it acts as the main fluid of the central nervous system. Both have three meninges: dura mater, arachnoid mater, and pia mater. Both brainstem and spinal cord are made up of nerve tissue. What is Brainstem      – Definition, Components, Function 2. In the spinal cord, white matter is more superficial than grey matter, and surrounds the different horns. They can also travel from other parts of the body, like the lung or breast, and form deposits in the brain or spinal cord; this is called a secondary cancer or brain metastases. The spinal cord is a single structure, whereas the adult brain is described in terms of four major regions: the cerebrum, the diencephalon, the brain stem, and the cerebellum. 2011 Apr;300(4):R844-54.

Figure 1 shows that with exception of succinate, SCM have 30–40% lower respiratory activities in metabolic state 3 and state 3U. doi: 10.1152/ajpregu.00528.2010. Spinal cord meninges are similar to brain meninges mentioned above. The brain dura mater forms dural folds while the spinal cord dura mater does not form dural folds. The spinal cord dura mater does not form dural folds. 2. Branching out from the spinal cord are smaller nerves that control motor and sensory functions. Brainstem: The brainstem is a part of the brain that connects the spinal cord to the brain. The spinal cord is a fragile bundle of nerves that plays an important role in sensation, movement of the limbs, control of the bowel and bladder and many other important functions. Furthermore, the three layers collectively act to resist external shocks reaching the brain. It can be said that the spinal cord is what connects the brain to the outside world. The spinal cord device consists of a pulse generator, a small wire that carries the current from a pulse generator to the nerve fibers of the spinal cord. Both brainstem and spinal cord transmit nerve impulses to the brain. Start studying Ascending and Descending Pathways of Spinal Cord and Brain. The white matter of the brainstem connects the body via the spinal cord. Furthermore, the spinal cord runs inside the spinal column while the spinal column is a bony structure. In this context, the dura mater forms dural folds in the brain, whereas it does not form dural folds in the spinal cord. The key difference between brain and spinal cord meninges is based on the characteristic features of the dura mater.The brain dura mater forms dural folds while the spinal cord dura mater does not form dural folds.. This is the key difference between spinal cord and vertebral column. Like the brain, the spinal cord is covered by three connective-tissue envelopes called the meninges.

All rights reserved. Function-wise, the brain serves as the centre for sensing, thinking, reasoning, remembering and sending executive commands to different parts of the body. 1. As the overseer of the majority of the body’s physiological processes, the brain has numerous connections with extracranial structures. However, there are minute differences between brain and spinal cord meninges. 1. The main difference between brainstem and spinal cord is the role of each component in the coordination of the functions of the body. It forms dural folds in the brain. The brain and the spinal cord form the central nervous system. The most-superior and the most complex region of the brainstem is the midbrain. There are three meninges in the brain: dura mater, arachnoid mater, and pia mater. What are the Similarities Between Brainstem and Spinal Cord      – Outline of Common Features 4.

The gray matter of the brainstem controls the cardiac and respiratory functions of the body such as breathing, body temperature, blood pressure, heart rate, digestion of food, hunger and taste. Motor impulses are also transmitted to the effector organs through the spinal cord. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Spinal Cord: The spinal cord runs through the vertebral column. Therefore, spinal nerves are referred to mixed nerves. Both notochord and nerve cord are characteristics features of chordates. Metabolic and functional differences between brain and spinal cord mitochondria underlie different predisposition to pathology. The spinal cord is responsible for coordinating simple reflexes that create involuntary muscular movements. Spinal cord refers to the cylindrical bundle of nerve fibers enclosed by the spine that connects all parts of the body to the brain. Moreover, it also gives rise to the blood-brain barrier in the spinal cord and the brain. Whereas, the pia mater lines the brain and spinal cord while producing CSF.

The dura mater provides protection to the brain and the spinal cord. The middle layer is the arachnoid mater. The spinal cord acts as one of the primary conduits through which the body and the brain exchanges information. Both brainstem and spinal cord are made up of nerve tissue. While white matter constitutes about 60% of the brain volume, grey matter makes up the other 40%. Spinal column is commonly known as the backbone which protects the spinal cord, which composed of cables of nerves.. Spinal Cord As brainstem is a component of the brain, its gray matter can be identified outside while its white matter can be identified inside. That is; the dura mater forms dural folds in the brain, whereas it does not form dural folds in the spinal cord. Thus, it gives rise to the blood-brain barrier by separating the brain from the rest of the organs. It is 40 to 50 cm long and 1 – 1.5 cm in diameter. As the spinal cord is also made up of nerve tissue, it is also composed of gray matter and white matter. The below infographic summarizes the difference between brain and spinal cord meninges, comprehensively. The arachnoid space is not as thick as the dura mater.
