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
The main function of sensory nerves is to carry sensory information from the body to the spinal cord. This information is then processed by the spinal cord and sent to the brain, where it is interpreted. Sensory nerves also carry signals from the brain to the body, allowing us to move and respond to our …
1. Chemical synapse: This type of synapse is the most common and involves chemical signaling between two neurons. 2. Electrical synapse: This type of synapse is less common and involves electrical currents passing through gap junctions between the two neurons. 3. Gap junction: This type of synapse is formed when two neurons are connected by …

Neurotransmitters are chemical messengers that enable the transmission of signals between neurons and other cells in the body. They are essential for the functioning of the nervous system and are involved in a variety of processes, including learning, memory, emotion, mood, and movement. Neurotransmitters are also involved in the regulation of appetite, sleep, and stress. …

A synapse is the small gap between two neurons that allows them to communicate with each other. When an impulse (action potential) is generated in one neuron, it is transmitted across the synapse to the next neuron. This is done by a process called neurotransmission. Neurotransmitters are released from the presynaptic neuron and bind to …
