Lecture Study Guide Chapter 1 - Key Concepts (Fill-in-the-Blank)

A set of fill-in-the-blank flashcards covering Chapter 1 study topics: anatomical position, cavities, serous membranes, imaging, homeostasis, feedback loops, gradients, and basic physiological concepts.

Homeostasis is the maintenance of a relatively internal environment.

stable environment

A negative feedback loop is a control mechanism that the initial stimulus.

counteracts

In a positive feedback loop, the response the stimulus.

reinforces

In anatomical terms, the body is assumed to be in the position.

anatomical

The term 'anterior' refers to the of the body.

front

The horizontal plane is also known as the plane.

transverse

The anterior body cavity is subdivided into the and cavities.

thoracic, abdominopelvic

The posterior (dorsal) body cavity contains the and the .

brain, spinal cord

The thoracic cavity is separated from the abdominopelvic cavity by the .

diaphragm

A major organ found in the right upper quadrant (RUQ) is the .

liver

A serous membrane is a double-layered membrane with a parietal layer that lines the cavity and a visceral layer that covers the .

organ

The layer that lines the cavity is called the layer.

parietal

The layer that covers the organ is the layer.

visceral

The three main serous membranes are the , the , and the .

pleura, pericardium, peritoneum

X-ray, CT, and MRI are forms of imaging.

medical

CT stands for tomography.

computed

MRI uses strong magnetic fields and waves to generate images.

radio

X-ray imaging primarily shows structures such as bones.

dense

The anatomical position provides a standard reference for describing body location and .

orientation

The main types of gradients are , , and .

chemical, electrical, and pressure

Cell-to-cell communication is important for activities across tissues.
