Homeostasis and Anatomical Terminology Notes

The study of the structures of the body and how the parts fit is ____________.

Anatomy

The study that describes the function of the body parts and how they work is ____________.

Physiology

Humans are ________________.

multicellular organisms

______________ is a condition of equilibrium through regulation and feedback.

Homeostasis

In negative feedback, the response reduces or stops the stimulus, preventing severe changes within the body. Most homeostatic controls are ____________ mechanisms.

negative feedback

Positive feedback enhances or magnifies the stimulus, resulting in an ____________ effect or cascade.

amplifying

Directional terms describe where a body part is located ____________ ____ ____________ _________________.

relative to another body part

A ___________ section divides the body into left and right.

sagittal

A ___________ or coronal section divides the body into front and back.

frontal

The ____________ body cavity is made up of the cranial cavity and the vertebral cavity.

dorsal

The ____________ body cavity is made up of the thoracic cavity and the abdominopelvic cavity.

ventral

Membranes lining cavities are _________ serosa and membranes covering organs are _________ serosa.

parietal; visceral

The major divisions of the abdominopelvic cavity include right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and ____________ ______________ (LLQ).

left lower quadrant

Homeostatic imbalance occurs when the control centre cannot properly respond to a stimulus, leading to ____________ and dysfunction.

disease

The anatomical position for a human is standing, feet slightly apart, palms facing forward, thumbs pointing ____________ from the body.

away

___________ is the branch of biology concerned with the structure and organization of the body.

Anatomy

___________ is the study of the functions and mechanisms in a living system.

Physiology

___________ refers to the body's ability to maintain a stable internal environment despite changes in external conditions.

Homeostasis

The significance of _____________ lies in its role in enabling organisms to survive and function efficiently in varying environments.

homeostasis

In _____________ feedback, the response enhances the original stimulus, leading to an amplified effect.

positive

___________ feedback mechanisms counteract changes in the body, helping to maintain homeostasis.

Negative

Homeostatic _____________ occurs when the body's regulatory systems fail to function correctly, leading to disease.

imbalance

The _____________ position is the standard reference point used to describe the location of body parts, involving standing with arms at the sides and palms facing forward.

anatomical

The major body cavities include the _____________ cavity, which houses the brain and spinal cord, and the _____________ cavity, which contains the thoracic and abdominopelvic cavities.

dorsal; ventral

The _____________ serosa lines body cavities, while the _____________ serosa covers the organs within those cavities.

parietal; visceral

The four quadrants of the abdominopelvic cavity are right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and _____________ _____________ (LLQ).

left lower quadrant

Each quadrant of the abdominopelvic cavity contains specific organs: the RUQ contains the _____________, the LUQ contains the _____________, the RLQ contains the _____________, and the LLQ contains part of the _____________.

liver; stomach; appendix; large intestine
