In anatomy, fissure (Latin fissura, Plural fissurae) is a groove, natural division, deep furrow, cleft, or tear in various parts of the body. Anatomy (from the Greek anatomia, from ana separate apart from and temnein, to cut up cut open is a branch of Biology that is the consideration Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Plural is a Grammatical number, typically referring to more than one of the Referent in the real world

Anatomy

Various types of anatomical fissure are:

Brain

• Fissure of Bichat: found below the corpus callosum in the cerebellum of the brain. The corpus callosum is a structure of the Mammalian Brain in the longitudinal fissure that connects the left and right Cerebral hemispheres It also facilitates The cerebellum ( Latin: "little brain" is a region of the Brain that plays an important role in the integration of sensory perception The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain
• Broca's fissure: found in the third left frontal fold of the brain.
• Burdach's fissure: connects the brain's insula and the inner surface of the operculum. The operculum is partly in the most posterior portion of the Inferior frontal gyrus of the Frontal lobe in the Brain.
• Calcarine fissure: extends from the occipital of the cerebrum to the occipital fissure. The calcarine fissure (or calcarine sulcus) is an anatomical landmark located at the very caudal end of the medial surface of the brain The telencephalon (tɛlɛnˈsɛfəlɒn cerebrum, or forebrain is the most Anterior or especially in humans most Dorsal region of the
• Callosomarginal fissure: found in the mesial surface of the cerebrum.
• Central fissure or Ronaldo's fissure: separates the brain's frontal and parietal lobes. The central sulcus is a fold in the Cerebral cortex of Brains in Vertebrates. The central sulcus is a fold in the Cerebral cortex of Brains in Vertebrates. The parietal lobe is a lobe in the Brain. It is positioned above (superior to the Occipital lobe and behind (posterior to the Frontal lobe.
• Clevenger's fissure: found in the inferior temporal lobe of the brain
• Collateral fissure: found in the inferior surface of the cerebrum. The collateral fissure (or sulcus) is on the tentorial surface of the hemisphere and extends from near the Occipital pole to within a short distance of the Temporal
• Hippocampal fissure: a fissure that extends from the brain's corpus callosum to the tip of the temporal lobe.
• Horizontal fissure or Transverse fissure: found between the cerebrum and the cerebellum. Transverse fissure is also found in the liver and lungs. The liver is a vital organ in the human body and is present in Vertebrates and some other animals lung is the essential Respiration organ in air-breathing Animals including most Tetrapods a few Fish and a few Snails The most primitive
• Occipitoparietal fissure: found between the occipital and parietal lobes of the brain.
• Fissure of Sylvius: separates the frontal and parietal lobes of the brain from the temporal lobe. The lateral sulcus (also called Sylvian fissure or lateral fissure) is one of the most prominent structures of the human Brain.
• Wernicke's fissure: separates the brain's temporal and parietal lobes from the occipital lobe.
• Zygal fissure: found in the cerebrum.

Skull

• Auricular fissure: found in the temporal bone
• Pterygomaxillary fissure
• Sphenoidal fissure: separates the wings and the body of the sphenoid bone. The temporal bones are situated at the sides and base of the Skull. The pterygomaxillary fissure is vertical and descends at right angles from the medial end of the Inferior orbital fissure; it is a triangular interval formed by the divergence The sphenoid bone (from Greek sphenoeides, "wedgelike" is a Bone situated at the base of the Skull in front of the Temporals and basilar Bones are rigid organs that form part of the Endoskeleton of Vertebrates They function to move support and protect the various organs of the body produce

Liver

• Longitudinal fissure: found in the lower surface of the liver, also a fissure that separates the right and left hemispheres of the cerebrum. The great longitudinal fissure (or longitudinal cerebral fissure, or longitudinal fissure, or interhemispheric fissure) is the deep groove which separates The liver is a vital organ in the human body and is present in Vertebrates and some other animals
• Portal fissure: found in the under-surface of the liver.
• Umbilical fissure: found in front of the liver.

Other

• Henle's fissure: the connective tissue between the muscle fibers of the heart. The heart is a muscular organ in all Vertebrates responsible for pumping Blood through the Blood vessels by repeated rhythmic
• Palpebral fissure: separates the upper and lower eyelids. Palpebral fissure is the Anatomic name for the separation between the upper and lower Eyelids In the adult this measures about 10mm vertically and 30 mm horizontally An eyelid is a thin fold of skin that covers and protects an Eye.

Abnormal fissure

Fissure can also mean unnatural tract or ulcer, most commonly found in the anus. The anus is an opening at the opposite end of an Animal 's Digestive tract from the Mouth. One of the most common types of fissure is anal fissure. An anal fissure is an unnatural crack or tear in the Anus skin

Other fissures

• Fissure vent: a volcanic vent that does not include explosive activity. A fissure vent, also known as a volcanic fissure or simply fissure, is a linear Volcanic vent through which Lava erupts usually without any

• Sulcus (anatomy)

A sulcus (pronounced with a hard c (pl sulci) is a depression or fissure in the surface of an organ especially the Brain.
