What is the sphenoid bone? The sphenoid bone (os sphenoidale) is a central bone of the skull that is roughly shaped like a flying wasp with outstretched wings and drooping legs: It consists of the sphenoid body (corpus), two large sphenoid wings (alae majores), two small sphenoid wings (alae minores) and the downward-pointing wing-like projections … Sphenoid Bone (Os sphenoidale): Anatomy & Function

As part of the os sphenoidale, the sella turcica forms a bony structure at the base of the skull. Within the saddle-shaped depression sits the pituitary gland, which is connected to the thalamus via the pituitary stalk. Hormonal processes in the human body are controlled from here. What is the sella turcica? The term “sella … Sella Turcica: Structure, Function & Diseases
The lacrimal nerve represents a branch of the ophthalmic nerve and sensitively innervates the conjunctiva (tunica conjunctiva) and parts of the eyelid. It is connected to the facial nerve and the zygomatic nerve. The latter gives fibers to the lacrimal nerve via a communication branch, which influence the lacrimal gland. What is the lacrimal nerve? … Lacrimal 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 anterior cranial fossa corresponds to the anterior cranial fossa and contains the olfactory bulb (bulbus olfactorius) and the frontal lobe (lobus frontalis) of the cerebrum. In addition, the anterior cranial fossa has four openings through which blood vessels and nerves pass. What is the anterior cranial fossa? Anatomy refers to the anterior cranial fossa … Fossa Cranii Anterior: Structure, Function & Diseases
The pterygopalatine fossa is an indentation in the human skull. It is located between the sphenoid bone and the maxilla. Alternatively, it is called the wing palatal fossa. What is the pterygopalatine fossa? The pterygopalatine fossa is a part of the human skull. It is a bulge or depression in the bone of the skull. … Fossa Pterygopalatina: Structure, Function & Diseases
The talus (talus) is part of the tarsus (tarsus) along with the calcaneus (heel bone), os naviculare (scaphoid bone), ossa cuneiformia (sphenoid bone) and os cuboidem (cuboid bone). The talus forms with its upper side, the trochlea tali (joint roll), a part of the upper ankle joint. Since the talus bears the entire weight of … Talus fracture
Diagnostics An important point of reference for the doctor is the medical history, i.e. the description of the situation in which the injury occurred. In addition, the physician will look at the mobility of the foot (motor function) and whether there is a loss of sensitivity (the sensation in and on the foot). X-rays in … Diagnostics | Talus fracture
Complications The blood supply to the talus is provided by several small vessels lying in a narrow space. These can be easily injured by dislocations. This is one of the reasons why the risk of osteonecrosis (death of the bone) is very high in the case of a talus fracture. For Hawkins I, the risk … Complications | Talus fracture
The lateral pterygoid muscle is a masticatory muscle of the human dentition. Through it, the opening of the jaw is ensured. In addition, it allows the jaw to be pushed forward. What is the pterygoid lateralis muscle? The pterygoid lateralis muscle is a muscle of the temporomandibular joint. It is located on the inside of … Lateral Pterygoid Muscle: Structure, Function & Diseases
The pterygoid medialis muscle is a muscle that belongs to the masticatory musculature in humans. It is located on the inside of the temporomandibular joint. Its function is to move the temporomandibular joint. What is the pterygoid medialis muscle? The pterygoid medialis muscle is a masseter muscle of the human dentition. Thus, it has an … Medial Pterygoid Muscle: Structure, Function & Diseases
