Sternocephalic
Referring to the sternocleidomastoid muscle, which is a large, strap-like muscle that runs from the sternum (breastbone) to the mastoid process of the temporal bone in the skull, playing a crucial role in movements such as rotating the head and tilting it to the side. The name itself is derived from the Greek words "sternon" meaning breastbone, "cleis," meaning clavicle, and "mastoid," meaning distant from the ear.
Sternochondral
Sterochondral refers to a type of bone or cartilage that connects the sternum (breastbone) to the ribs.
Sternoclavicular
The term "sternoclavicular" refers to the junction or region where the sternum (breastbone) and the clavicle (collarbone) meet, forming a joint. <br><br>In anatomy, the sternoclavicular joint is a complex joint that connects the clavicle (collarbone) to the manubrium (upper part of the sternum). It is a pivot joint, which allows for rotational movement between the clavicle and the sternum, enabling actions such as raising the arm or throwing motions.<br><br>Radiologically and orthopedically, the term is also used in relation to the process of dislocation or injury of the joint, where the clavicle comes apart from its connection to the sternum.
Sternocleidomastoid
The sternocleidomastoid (SCM) muscle is a paired muscle of the neck, which plays a crucial role in the movement of the head and neck.<br><br>The name "sternocleidomastoid" is derived from three distinct parts:<br><br>1. "Sterno-": referring to the sternum (breastbone)<br>2. "Cleido-": referring to the clavicle (collarbone)<br>3. "Masto-": referring to the mastoid process (a bony prominence behind the ear)<br>4. "-oid": indicating that the muscle lies under the structures above the ones mentioned (sternum, clavicle, and mastoid process)<br><br>The sternocleidomastoid muscle arises from two separate points, the sternum and clavicle, and combines to form a single muscle that inserts into the mastoid process. This unique anatomy implies that the muscle is responsible for the extension and lateral flexion of the head and neck.<br><br>Some of its key functions include:<br><br>1. Assisting in rotating and flexing the head<br>2. Stabilizing the head and neck during movements<br>3. Helping to maintain posture<br>4. Supporting the structures of the vertebral column<br><br>Anatomically, the sternocleidomastoid muscle is susceptible to injury and is one of the sites of muscle attachment for various conditions, including fibromyalgia and cervical dystonia.
Sternocleidomastoideus
The sternocleidomastoideus, also known as the sternocleidomastoid muscle (SCM), is a paired muscle of the neck in the human body.<br><br>It's a long, fan-shaped muscle that plays a crucial role in neck movements and maintaining posture. The name itself provides a hint at its dual attachments and function:<br><br> "Sterno" refers to the sternum (breastbone)<br> "cleido" refers to the clavicle (collarbone)<br> "mastoid" refers to the mastoid process, a part of the temporal bone in the skull<br><br>This muscle is involved in:<br><br>1. <strong>Movements of the head</strong>: Rotating the head to the opposite side ( ipsilateral rotation) and lifting it up with the help of the trigeminal nerve.<br>2. <strong>Posture</strong>: Supporting and maintaining proper head posture by contracting the muscle to reduce strain on the neck and back.<br>3. <strong>Facial expressions</strong>: Showing toleration or sympathy, such as rolling one's eyes (ever been there?).
Sternocostal
In the context of human anatomy, "sternocostal" refers to a structure that is located between the sternum (breastbone) and the ribs.<br><br>More specifically, it can refer to:<br><br> Sternocostal joint (also known as the sternocostal articulation): a type of joint that connects the sternum to the ribs.<br> Sternocostal muscle: one of the muscles of the chest, which connects the sternum to the ribs.<br> Sternocostal angle (or sternal angle): an anatomical landmark that marks the boundary between the manubrium (upper part) and the body (lower part) of the sternum.<br><br>The prefix "sterno-" comes from the Latin "sternum," meaning breastbone or chest; "costal" comes from the Latin "costa," meaning rib.
Sternohyoid
The sternohyoid muscle is one of the neck muscles. It originates from the sternum (breastbone) and inserts into the hyoid bone of the neck. This muscle is involved in swallowing and helps to depress the hyoid bone, thus aiding in tongue and larynx movements during swallowing.
Sternomastoid
The sternomastoid is a muscle in the neck that connects the breastbone (sternum) to the mastoid process of the temporal bone in the skull. It is a bilateral muscle that plays an essential role in the movement of the neck and head. The sternomastoid muscle has two heads, the sternal head and the mastoid head, and it is innervated by the accessory nerve. It is involved in movements such as flexing the neck, rotating the head, and stabilizing the scapula.<br><br>The sternomastoid muscle is sometimes referred to as the "sternocleidomastoid muscle" or "SCM" muscle.
Sternorrhyncha
A somewhat obscure one!<br><br>Sternorrhyncha is a suborder of insects in the order Hemiptera (true bugs). <br><br>The term is derived from the Greek words "sterno-", meaning "chest" or "breast", and "rhyncha", meaning "snout".<br><br>Sternorrhyncha belongs to a group of insects with a relatively primitive body structure, characterized by a short, stout snout.
Sternoschisis

Sternothyroid
Sternothyroid refers to something that resembles or is related to the sternothyroid muscle. Specifically, it can refer to the sternothyroid muscle itself, which is a muscle in the neck that connects the posterior borders of the hyoid bone and the posterior border of the greater horn of the hyoid process of the thyroid cartilage, or to the region or area where this muscle is located.<br><br>In a broader sense, sternothyroid can also refer to anything else related to this area of the neck, such as injuries, masses, or pathologies that occur in this region.<br><br>It can also refer to the sternothyroid method, a surgical approach used in neck dissection to avoid damage to the sternothyroid muscle.<br><br>It is often used in medical contexts to describe conditions or anatomy that affects the sternothyroid region of the neck.
Sternotomy
A sternotomy is a surgical incision made in the sternum, or breastbone. It is typically performed during open-heart surgery to access the heart. The sternum is divided by a saw or a specialized instrument, and a retractor is used to keep it apart, allowing the surgeon to operate on the heart. The incision is usually closed with wire or stitches after the surgery.
Sterns
Stemming from the word "stern", sterns can refer to:<br><br>1. A stern (back section) of a boat or ship: The stern is the rear section of a boat or ship, often with a flat bottom.<br>2. Stern look or strict expression: A stern look can be an intimidating and disapproving expression on someone's face.<br>3. Supporting structure or pole (mainly nautical): A stern can also refer to a vertical or sloping structure attached to the back of a ship, which helps to stabilize it.<br><br>However, a more interesting meaning of "sterns" is related to a type of stern or back sterns on sailboats or old sailing ships.

Steroidogenesis
Steroidogenesis is the process by which cells convert cholesterol into steroids, which are a group of compounds that play a wide range of biological roles. Steroidogenesis is an essential process in the biosynthesis of steroid hormones, such as aldosterone, cortisol, and estrogen, among others.<br><br>The process of steroidogenesis occurs through a series of enzyme-catalyzed reactions, which involve the conversion of cholesterol into different steroids through a series of intermediate steps. Each step in the pathway is catalyzed by a specific enzyme, and the overall process is tightly regulated by various feedback mechanisms to ensure that the production of steroids is carefully controlled.<br><br>Steroidogenesis occurs in specific cells, such as the adrenal cortex, gonads (ovaries and testes), and placenta, and is under the control of various hormones and signaling pathways. The process is essential for maintaining homeostasis, regulating growth and development, and responding to stress.<br><br>Dysregulation of steroidogenesis has been implicated in various diseases, including cancer, metabolic disorders, and congenital adrenal hyperplasia, among others.
Steroidogenic
Steroidogenic refers to the process by which the body produces steroids, which are a group of hormones that have a four-ring structure. steroidogenic cells or tissues are responsible for synthesizing these steroid hormones from cholesterol, a type of lipid.<br><br>For example: The adrenal cortex is a steroidogenic gland located on top of the kidneys that produces steroid hormones such as cortisol and aldosterone.
Steroids
Synonyms: anabolic steroids, performance-enhancing drugs (PEDs)<br><br>Meaning: A type of synthetic hormone that increases muscle mass and can be used to improve athletic performance, often in an unethical or illegal manner.<br><br>Example sentences:<br>- The athlete was accused of taking steroids to gain an unfair advantage in the competition.<br>- The use of steroids in sports is a major concern due to the health risks associated with them.<br>- Steroids can have serious side effects, including liver damage and aggression.
