The common carotid plexus is a nerve plexus in the human organism. This is a network of different nerves that connect their fibers. The common carotid plexus consists of sympathetic nerve fibers. What is the common carotid plexus? In the human organism, there is a plexus of nerves, lymphatic vessels, veins or arteries in various … Common Carotid Plexus: Structure, Function & Diseases
The dura mater (hard meninges) serves essentially to protect the brain from external influences. It is one of three meninges that surround the human brain. This three-layered meninges (meninx encephali) consists of connective tissue and merges in the spinal canal into the so-called spinal cord skin. The hard meninges are particularly taut, lie on the … Dura Mater: Structure, Function & Diseases
The tentorium cerebelli is a skin in the brain and separates the posterior fossa (fossa cranii posterior) from the middle fossa (fossa cranii media). The brainstem protrudes through the tentorial slit (incisura tentorii). Tears in the tissue can cause hemorrhage, possibly leading to midbrain syndrome. What is the tentorium cerebelli? The tentorium cerebelli represents an … Tentorium Cerebelli: Structure, Function & Diseases
The posterior meningeal artery is a blood vessel branch supplying the posterior meninges. It is connected to the external carotid artery through the opening in the base of the skull (foramen jugulare). Diseases in this context include meningitis (meningitis), meningiomas (tumors of the meninges), hematomas (hemorrhages), malformations (malformations) of the vessels, arteriosclerosis (deposits in the … Posterior Meningeal Artery: Structure, Function & Diseases
The abducens nerve is the VIth cranial nerve. It is responsible for the movement of the eyeball. It is composed primarily of motor fibers and innervates the lateral straight muscle. What is the abducens nerve? The abducens nerve is the VIth of the total XII. Cranial Nerves. Like most other cranial nerves, it supplies areas … Abducens Nerve: Structure, Function & Diseases
The protuberantia occipitalis interna is a part in the skull of the human body. It is associated with the occipital bone. It is a bony prominence called the protuberantia occipitalis interna. What is the internal occipital protuberance? The protuberantia occipitalis interna is called the internal occipital protuberance. It is a small part of the human … Protuberantia Occipitalis Interna: Structure, Function & Diseases
The maxillary nerve is part of the V. Cranial Nerve. It supplies a large area of the face. In particular, it innervates the area below the eyes to the jaw. What is the maxillary nerve? The maxillary nerve is classified under the V cranial nerve. This is the trigeminal nerve. The V. cranial nerve is … Maxillary Nerve: Structure, Function & Diseases
The foramen lacerum is an opening in the human skull. It is used as a passageway for nerve fibers. This pathway can provide nerve supply to the outer and inner regions of the skull. What is the lacerated foramen? The foramen lacerum is a small opening in the skull. The human skull is made up … Foramen Lacerum: Structure, Function & Diseases
The spinal cord skin is the term used to describe the structured connective tissue that surrounds the entire spinal cord in layers. However, from the spinal cord, the spinal cord skin extends upward (cranially) toward the head, where it eventually merges with the meninges through the foramen magnum (the opening at the back of the … Spinal Cord Skin: Structure, Function & Diseases
The pia mater is the innermost meninges and nestles against the surface of the brain, also reaching the fine interstices of the cerebral convolutions (gyri) and folds (sulci). Together, the three meninges help protect the brain. The permeability of the pia mater is significant for the blood–brain barrier, the exchange of substances between cerebral fluids, … Pia Mater: Structure, Function & Diseases
The spinal canal is referred to as the vertebral canal. The spinal cord and the cauda equina run through it. What is spinal canal? The vertebral canal (canalis vertebralis) is a canal formed by superimposed vertebral holes in the spine. Its course extends from the first cervical vertebra through the cervical spine (C-spine), thoracic spine … Vertebral Canal: Structure, Function & Diseases
The falx cerebri separates the two hemispheres in the cerebrum. It is a crescent-shaped membrane. It is composed of hard meninges. What is the falx cerebri? The falx cerebri is classified as part of the central nervous system and is located inside the skull. The cerebrum consists of two halves. These are also called hemispheres … Falx Cerebri: Structure, Function & Diseases
