The medulla oblongata is a part of the brain stem that plays an important role in the regulation of autonomic functions such as breathing, heart rate, blood pressure, and digestion. It also serves as a connection between the brain and spinal cord. The medulla oblongata is located in the lower part of the brainstem, just …
The cerebellum is a region of the brain located at the back of the head that is responsible for coordinating and controlling movements, balance, and posture. It is also involved in some cognitive functions such as attention and language, and has been implicated in some emotional control. It consists of two hemispheres and is divided …
The thalamus is a complex structure located in the centre of the brain. It is composed of several interconnected nuclei that are involved in many different functions, including relaying sensory information to the cerebral cortex, regulating consciousness, sleep, and alertness, and playing a role in motor control. The thalamus also plays a role in the …
Cerebrum is the largest part of the brain and is responsible for many of the brain’s most important functions, such as consciousness, memory, language, and problem-solving. It is divided into four distinct lobes: the frontal, parietal, occipital, and temporal. Each of these lobes has its own distinct functions, but all four work together to control …
1. The Skull: The skull is the primary protective structure for the brain, providing both a hard, outer shell as well as cushioning within the cranium. 2. Meninges : The meninges are layers of tissue that surround and protect the brain and spinal cord. 3. Cerebrospinal Fluid: The cerebrospinal fluid is a clear, colourless liquid …
The peripheral nervous system (PNS) is the part of the nervous system that lies outside of the brain and spinal cord. It is made up of nerves and ganglia and is responsible for carrying information to and from the central nervous system to the rest of the body. The PNS is composed of two components: …
The central nervous system consists of the brain and spinal cord. The brain is composed of the cerebrum, cerebellum, and brainstem. It is responsible for controlling voluntary and involuntary body functions, such as breathing and heart rate, and processing sensory information from the body and environment. The spinal cord is a long, thin bundle of …
The nervous system is a complex network of nerve cells and pathways that transmits signals between different parts of the body. It is responsible for coordinating movement, sensory information, and thoughts. It is divided into two parts: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes …
Mixed nerves are nerves that contain both motor and sensory axons. The primary function of mixed nerves is to carry signals from the spinal cord to the body, and to carry sensory information from the body back to the spinal cord. They are responsible for controlling movement for carrying sensation from the skin and other …
The main function of a motor nerve in the spinal cord is to carry signals from the brain to the skeletal muscles, allowing us to move our body parts. Motor nerves also carry signals from the brain to the smooth and cardiac muscles, allowing us to regulate our internal organs. brain, spinal cord
