Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video describes the examination of the ear, beginning with a review of its surface and interior anatomy (Figure 1). The cartilaginous auricle consists of the helix, antihelix, earlobe, and tragus. The mastoid process is positioned just behind the earlobe. The slightly curving auditory canal ends at the tympanic membrane, which transmits sound...

The Central Dogma

Overview The central dogma of biology states that information encoded in the DNA is transferred to messenger RNA (mRNA), which then directs the synthesis of protein. The set of instructions that enable the mRNA nucleotide sequence to be decoded into amino acids is called the genetic code. The universal nature of this genetic code has spurred advances in scientific research, agriculture, and medicine. RNA Is the Missing Link between DNA and Proteins In the early 1900s, scientists discovered...

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the...

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Changes in vessel diameter alter blood flow through the ear’s vascular network. When vessels widen or narrow, the amount of oxygenated blood reaching surrounding tissues changes, influencing metabolic support and heat transfer. This makes diameter-dependent flow regulation useful for examining how peripheral circulation responds to physiological or experimental conditions.
Local blood flow connects vascular delivery with tissue exchange. As blood moves through the network, surrounding tissues receive oxygen and support for metabolism, while heat transfer can change with circulation. Studying these linked processes helps biology researchers relate visible vascular behavior to the functional condition of living peripheral tissue.
Its accessible vascular arrangement allows researchers to examine changes in circulation within living tissue. Observing the vessels and measuring blood flow can reveal how the microvascular system responds to altered conditions, including inflammation or experimental treatments. The resulting information links vascular anatomy with functional regulation rather than treating the vessel as an isolated structure.
Researchers can use the ear’s accessibility to visualize its vessels and measure circulation. These observations provide information about blood-flow behavior and changes in the surrounding vascular network. In biology experiments, combining visual assessment with circulation measurements helps identify vascular responses and evaluate how conditions or treatments affect peripheral microvascular function.
The central ear artery can be examined when a study focuses on microvascular function, vascular responses, inflammation, or the effects of an experimental treatment. Its vascular network provides a living tissue setting in which researchers can assess changes in circulation and relate those changes to broader biological processes occurring in peripheral tissues.
Studies can show how blood flow is regulated in living tissue and how vascular behavior changes under experimental conditions. Researchers may use the resulting observations to assess microvascular function, characterize responses associated with inflammation, or examine treatment effects. These outcomes also strengthen understanding of how vascular anatomy supports tissue metabolism and heat transfer.
