The nervous system of snails, like that of all molluscs, is basically different from vertebrate nervous systems. She was a person who looked at science through a philosopher’s eye. It was the skeletal system diagram that helped me understand the “skeleton” of human bodies. It supplies cutaneous branches to the skin of the leg and foot in the region between the knee and the ankle. To be precise, the brain is placed in the cranial cavity and the spinal cord in the spinal cavity. II.

She used to say, “The human body systems are the most accurately engineered machines that possess an intellect of their own. Peripheral system nerves branch from either the brain stem or the spinal cord. These neurons can only send information one way. The human nervous system can be divided into two parts, central and peripheral. Let’s take a closer look at the central nervous system parts and functions. The nervous system consists of the brain, spinal cord, and nerves. Lumbar PlexusFormed by the ventral divisions of the first four lumbar nerves, the lumbar plexus is located in the lumbar region of the body. These include the squid giant synapse, the neuro-muscular junction of certain somatic muscles, the chromatophores, the statocysts, the ink-gland and the central nervous system.

The food is taken to the stomach region and then taken to what is known as the caecum. The afferent ones conduct signals from sensory neurons to the central nervous system, while the efferent ones conduct signals from the central nervous system along motor neurons to muscles or glands. Their nervous system is developed to a much higher degree than that of other molluscs. Respiratory Organs 6. Obturator NerveIt is a mixed nerve that arises from the lumbar plexus. And understanding complexities can never be simple. Phosphoric Triester Hydrolases Cyanides Diynes Homeodomain Proteins Dopamine beta-Hydroxylase Transcription Factors Elements Plastics. Nerves are found only in the peripheral nervous system. For example, controlling body movements and receiving external stimuli. The CNS receives input from a variety of different sources, and implements an appropriate response to the stimuli, in a cohesive manner. The Nervous System is Categorized by Function and Structure. Glia or glial cells, as they are called, are non-neural cells that play a vital role in maintaining homeostasis and protecting the brain’s neurons. So here are some interesting facts about the nervous system. The nervous system can suffer from a number of afflictions, including cancer (e.g., brain tumors).

The optic lobe, (Royal Society) [J. The peripheral nervous system consists of a network of nerves that connects the rest of the body to the CNS. It is enveloped by a set of membranes known as meninges that protect the brain and the spinal cord. The nervous system is divided into two branches: CNS (central nervous system) & PNS (peripheral nervous system). The cerebrum is associated with information storage and processing; the cerebellum is responsible for balance, posture and coordination of movements; and the brain stem plays a vital role in controlling breathing and heart rate along with some other important body processes.

Functionally, the peripheral nervous system can be divided into two parts; the somatic nervous system and the autonomic nervous system, the somatic nervous system is responsible for bodily activities that are under conscious control. External Features of Pila Globosa 3. It consists of about 13,500,000 neurons. The sympathetic nervous system governs the bodily responses to impending dangers, while the parasympathetic system is responsible for bodily actions that help in relaxation of body organs that are hyperactive. This is the way the body communicates with the brain and vice versa. It is through the peripheral nervous system. It is the largest nerve which is unprotected by muscle or bone. The thought of diagrams brought back memories of school days; the scent of those textbooks; the sight of the classroom and my teacher’s voice that said, “C’mon class, open your science books, page 41, chapter 3, Human Body Systems”.
