1. What is Adolescence?

Adolescence is the stage that extends from approximately 12-13 years until the end of the second decade of life. It is a transition stage in which one is not a child, but in which one is not yet an adult. Erikson calls this status the waiting period that society gives to its young members as they prepare to exercise their adult roles. The incorporation of adolescents into adult status has been delayed considerably.

The Biological Process of Puberty

Puberty is a set of physical changes that, throughout the second decade of life, transforms the child's body into an adult body capable of reproduction; it is a universal phenomenon for all members of our species. The adolescent psychosocial period, which lasts several years,...

Nonassociative Learning Mechanisms

Nonassociative learning corresponds to a form of implicit learning, stored in implicit memory, and represents the most elemental type of learning. The primary mechanisms discussed are Habituation and Sensitization.

Habituation

• Involves the depression (homosynaptic) of synaptic transmission.
• Occurs due to the inactivation of calcium channels, leading to a decrease in the inventory of neurotransmitter vesicles and their mobilization.
• Short-term Habituation (STH): Achieved with approximately 10 repetitive stimuli.
• Long-term Habituation (LTH): Requires over 40 repetitive stimuli.

Sensitization

Sensitization involves a modification of synaptic connections at the ion level, affecting sensory neurons, interneurons, and motor...

Fisiologia da Digestão: Biologia II

Conceitos Gerais da Digestão

Digestão: Degradação de macromoléculas em moléculas menores para melhor absorção.

Digestão Mecânica: Ocorre através da ação de movimentos físicos, tais como mastigação, deglutição e movimentos peristálticos.

Digestão Química: É a ação de sucos enzimáticos, tais como o suco gástrico, pancreático e entérico.

Órgãos do Aparelho Digestório

Boca

• Apresenta estruturas e glândulas anexas como dentes, língua e glândulas salivares (parótidas, sublinguais e submandibulares).
• Nela ocorre a digestão mecânica (mastigação e deglutição) e a digestão química (ação da saliva).
• Na saliva existe a enzima amilase salivar (também chamada de ptialina), que digere

Environmental Influence on Health

Health determinants are the conditions that influence health status. These are distinguished by physical, social, and political influences within a social organization.

Determinants of Health Factors

• Food: Linked to lifestyle.
• Pollution: Environmental factors.
• Obesity: Linked to biology and lifestyle.
• Alcohol: Linked to lifestyle.
• Hereditary Diseases: Linked to biology.

Health Determinants Changed by Human Activity

Environmental factors can change because we can alter the area where we live or move to another country. Factors linked to lifestyle and healthcare assistance change because we can choose our diet, decide whether to use drugs, and manage our medical care.

Defining Health and Well-being

Health is a state of equilibrium, the combination of physical, mental, and social well-being. It is the result of balanced feeding and personal care, mental well-being, and healthy activities. It involves the acceptance of oneself and transmitting a positive attitude to deal with feelings and problems. Well-being is the ability to relate to healthy people.

Disease and health in people are conditioned by various factors:

• Genetic
• Biological
• Environmental
• Personal

Factors Conditioning Health

Genetic Factors

• Genetic Diseases: These diseases develop (many at birth or years later) and are caused by mutations. Some genes are responsible for diseases that affect the structure of the body and metabolism.
• Congenital Malformations:
