Traumatic injuries can range from minor wounds to major, complex injuries causing shock and multi-system organ dysfunction. Trauma is the leading cause of death in patients between the ages of 15 and 24. It accounts for approximately 30% of all ICU …

Hemoglobin is an oxygen-binding protein found in erythrocytes that transports oxygen from the lungs to tissues. Each hemoglobin molecule is a tetramer made of four polypeptide globin chains. Each globin subunit contains a heme moiety formed of an …

The digastrics are a pair of muscles individually made up of two distinct muscle bellies: the anterior and posterior digastrics. They derive embryonically from the first and second pharyngeal arches. Together, they function in swallowing, chewing, …

The superior colliculus is a paired structure in the rostral midbrain that is involved in incorporating environmental stimuli and coordinating gaze shifts involving both eye and head movements. It is known as the optic tectum in other vertebrates and…

The superficial peroneal nerve is also known as the superior fibular nerve. The superficial peroneal nerve originates from the common peroneal nerve alongside the deep peroneal nerve. The superficial peroneal nerve is the smaller of the two…

Eclampsia is a uniquely pregnancy-related disorder that manifests as new onset of generalized tonic colonic seizures. It typically occurs after 20 weeks of concluded gestation, although it may occur sooner with plural gestations or molar pregnancies,…

Uterine atony refers to the corpus uteri myometrial cells inadequate contraction in response to endogenous oxytocin that is released in the course of delivery. It leads to postpartum hemorrhage as delivery of the placenta leaves disrupted spiral…

Twin births account for approximately 3% of live births and 97% of multiple bouts in the United States. In the absence of assisted reproductive technology, dizygotic twins are far more common than monozygotic twins and account for 70% of all twin…

Normal labor is characterized by regular and painful uterine contractions that conclude in progressive in labor. A discussion on abnormal labor patterns is reviewed as abnormalities of the first stage (cervical dilation to complete cervical dilation)…

This article reviews of methodologies for the induction of uterine contractions so that labor may occur. Physicians induce labor to promote vaginal delivery and to prevent complications of obstetric intervention. These complications are diverse and…

The deep petrosal nerve is a branch from the internal carotid plexus.[1] The plexus is located on the lateral side of the internal carotid as it courses superiorly. The deep petrosal enters the skull through the carotid canal with the internal…

The deep peroneal nerve is also known as the deep fibular nerve. It originates after the bifurcation of the common peroneal nerve between the upper segment of the peroneus longus and the head of the fibula.[1] The common peroneal nerve (spinal nerves…

Duplex ultrasound is a specialized interpretation of ultrasound waves and an integral tool in medical diagnosis and therapy today. Duplex ultrasonography combines the principles of anatomic and flow ultrasonography to deliver diagnostic information…

The mediastinal compartment contains multiple critical organs and vessels and serves as the central hub for lymphatic drainage. The mediastinum is classically subdivided into three functional divisions: anterior (pre-vascular), middle (visceral), and…
