The Human Body: Skeletal, Muscular, and Endocrine Systems
The Skeletal System
The skeletal system is made up of bones and joints. Bones are hard, light, and strong structures that form the framework of the body and provide protection for some organs. In locomotion, bones act as rigid levers moved by muscles.
Divisions of the Skeleton
The skeleton is divided into two zones:
- Axial skeleton: Consisting of the skull, vertebral column, and thoracic cage.
- Appendicular skeleton: Consisting of the thoracic and pelvic girdles and limbs.
- Shoulder girdle: Includes two

Item 5: 17th Century Philosophy
5.1. Historical Context
The 17th century concluded processes begun in the Renaissance (humanism, Reformation, technical advances). It is the century of new science, represented by Galileo, which shaped Bacon’s concept of science: “Man can conquer nature, and the instrument for this is science.” This era introduced the hypothetical-deductive method:

1. Technology and Technique
1.1 Defining Technology
The technique is an ability that transforms into a natural reality within an artificial one (Ortega y Gasset).

Precambrian Era
The Iberian Peninsula was located between the African (Gondwana) and European (Laurasia) continental plates, separated by the Tethys Sea. Orogenic movements during this era had minimal impact, primarily affecting the Galician-Leonese Massif, the western Asturian-Leonese Massif, and parts of the Toledo Mountains and Central System.
Paleozoic Era
The Hercynian orogeny, characterized by strong lateral pressures, began during the Carboniferous period. This resulted in the formation of mountain

Social Reaction and the Labeling of Deviance
The Focus of Social Reaction or Labeling Theory
Rejecting genetic, psychological, or multifactorial explanations of crime and deviance, labeling theory emphasizes the social construction of deviance. This perspective highlights the relative nature of social norms and the impact of labels applied to those who violate them. What is deviant for one person may not be for another, and what is considered deviant in one context may not be in another.

Types of Functions
C utilizes two main types of functions:
- Library Functions: Pre-written routines for common operations and calculations.
- User-Defined Functions: Created by programmers for specific tasks within their programs. These can also be part of modules or libraries.
Functions in C
A C function is a self-contained block of code designed to perform a specific task. It’s essentially a mini-program that produces a value or outcome based on its input arguments (parameters).
