Study Notes

Sections and Planes of Section

A longitudinal section cuts through the long axis of an organ.
A transverse section (or cross-section) cuts at a right angle to the long axis.
An oblique section is made at an angle other than a right angle.

Body Cavities

The body contains cavities that house internal organs, primarily the dorsal and ventral cavities.
Both major cavities are further subdivided into specific regions.

Serous Membranes

Serous membranes line trunk cavities and cover the respective organs, secreting fluid to reduce friction.
The parietal membrane lines the cavity wall, while the visceral membrane covers the organs.
Examples include:
- Pericardial cavity surrounds the heart.
- Pleural cavities surround the lungs.
- Peritoneal cavity surrounds abdominal and pelvic organs.

Human Body Study Overview

Objectives include defining anatomy, understanding organ systems, and maintaining homeostasis.
The course emphasizes participation in discussions and completion of tasks for understanding.

Body Positions

The anatomical position is upright with the head level, eyes forward, arms at sides, and palms facing forward.
Prone position: lying face down.
Supine position: lying face up.

Directional Terms

Directional terms describe body parts relative to each other, generally in pairs of opposites.

Body Regions

The body can be divided into regions:
- The trunk consists of the thorax, abdomen, and pelvis.
- Upper limbs consist of the arm, forearm, wrist, and hand.

Levels of Organization

Six structural levels of organization:
- Chemical: Interaction of atoms to form molecules.
- Cell: Basic unit of organisms, containing hereditary information.
- Tissue: Groups of similar cells (epithelial, connective, muscle, nerve).
- Organ: Multiple tissue types functioning together (e.g., heart, stomach).
- Organ System: Groups of organs working together (e.g., urinary system).
- Organism: A complete living entity, from single cells to complex beings.

Homeostasis

Defined as the maintenance of stable internal conditions, such as temperature.
It involves a feedback mechanism with:
- Receptor: Monitors condition and sends information to control center.
- Control Center: Compares input to set point and sends output commands to effectors.
- Effector: Produces a response that alters the controlled condition.
Negative feedback restores conditions to set point (e.g., blood pressure).
Positive feedback amplifies changes (e.g., childbirth contractions).
