Anatomical Chart The Brain

Product Information

The optic nerve conveys sensory information to the brain regarding your sense of vision. III. Oculomotor nerve The vagus nerve is involved with motor, sensory and parasympathetic functions. The motor part of the vagus nerve gives off movements in your throat responsible for the initiation of swallowing. The sensory part of the vagus nerve gives you sensation on the outer part of your ear, in your throat, your abdominal organs and heart, and contributes to your sensation of taste. The parasympathetic part of the vagus nerve regulates your heart rhythm and innervates your lungs and gastrointestinal tract. XI. Accessory nerve

The oculomotor nerve helps control the muscle movements of your eyes. It also constricts the pupil exposed to bright lighting and helps your lens adjust when looking at near or far objects. IV. Trochlear nerve The olfactory nerve is the first and shortest of the cranial nerves. It conveys sensory information related to your sense of smell. II. Optic nerve The circle of Willis is found on the inferior (bottom) side of the brain and is responsible for supplying oxygenated blood to more than 80% of the cerebrum. It is composed of the anterior cerebral arteries, anterior communicating artery, internal carotid arteries, posterior cerebral arteries, and posterior communicating arteries.

Exercising the Brain

The brainstem connects the brain to and is structurally continuous with the spinal cord. It is responsible for involuntary functions such as breathing, heart rate, sleep cycles, vomiting, digestion, coughing and sneezing and several other autonomic functions. The brainstem consists of the medulla oblongata, pons, and midbrain. The cerebrum is the uppermost and largest part of the brain. It is split by a central fissure into the right and left hemispheres and is also divided into four major lobes. The cerebrum controls several functions such as learning, emotions and movement, to name a few. The facial nerve is the nerve involved with your facial expression, sense of taste and sensation of your ear. It comprises three different nuclei: the motor nucleus, the parasympathetic nuclei and the sensory nucleus. VIII. Vestibulocochlear nerve

The temporal lobes are the second-largest lobes of the brain, located behind the ears. They are involved with memory, hearing, organisation and understanding language. Occipital lobe The parietal lobe is located above the temporal lobe and between the frontal lobe and occipital lobe. Containing the sensory cortex, it is responsible for the sense of touch, pain and temperature. It is also responsible for interpreting language, hearing, memory, and spatial and visual perception. Temporal lobe Our human brain anatomy art print has been designed by aǨprofessional medical illustrator so is anatomically correct as well as beautiful to view! The occipital lobe is the smallest lobe of the brain, located posterior to the parietal and temporal lobes, lying beneath the skull’s occipital bone. It is responsible for interpreting vision. Designed by our professional medical illustrators and exclusive to AnatomyStuff, the brain anatomy poster shows the following, fully labelled anatomical details:Printed onǨpremium-quality heavyweight fine art paper with a matt finish, the brain art print is ideal for framing, or we can frame it for you! Printed in the UK with UV resistant inks. The following size options are available, please select from the drop-down box: The human brain is the most complex part of our body and the organthat defines our humanity. The brain is composed of three major sections: The cerebrum, cerebellum, and brainstem. The main blood supply to the brain comes from the carotid arteries and the vertebral arteries. The carotid arteries branch off from the aorta (the largest artery in your body found by the heart) and are broken into the internal and external carotid artery. The internal carotid artery and the vertebral arteries come together to form an anastomosis, a complex network of blood vessels that provide an alternative route for blood to move through if an injury to the brain occurs. This particular anastomosis is called the circle of Willis. Circle of Willis The trochlear nerve is also involved with the movements of your eyes by supplying the superior oblique muscle. It allows your eye to point downward and inward. V. Trigeminal nerve
