The human nervous system comprises interconnected networks controlling bodily functions, featuring the sistema nervoso periferico e suoi componenti and endocrine regulation. The struttura e funzione del cervello umano works alongside hormonal systems, while funzione degli ormoni durante l'adolescenza plays a crucial role in development.

  • The peripheral nervous system extends throughout the body via nerve networks
  • The central nervous system (brain and spinal cord) processes information and coordinates responses
  • The endocrine system releases hormones for various bodily functions
  • Specialized sensory organs like the eyes enable perception of the environment
  • Neural tissue consists of interconnected neurons with myelin-covered extensions

Page 2: Brain Structure and Organization

The brain is divided into two hemispheres connected by the corpus callosum, with distinct regions responsible for different functions. The cerebral cortex contains specialized areas for processing sensory information and controlling motor functions.

Definition: The cerebral cortex is the outer layer of the brain containing billions of neurons that process information.

Highlight: Despite being only 2% of body weight, the brain uses 20% of the body's oxygen supply.

Example: Broca's and Wernicke's areas in the left hemisphere specifically handle language processing.

Vocabulary: Circumvolutions - The folds and ridges of the cerebral cortex that increase surface area.

Page 3: The Cerebellum and Spinal Cord

The cerebellum coordinates movement and balance, while the spinal cord serves as the main communication pathway between the brain and body. The spinal cord contains important nerve centers that regulate vital functions.

Definition: The spinal cord is a cylindrical bundle of nerve fibers that connects the brain to the rest of the body.

Highlight: Neural pathways cross over, meaning the left side of the brain controls the right side of the body and vice versa.

Page 4: The Peripheral Nervous System

The peripheral nervous system consists of nerves that connect the central nervous system to the rest of the body, divided into somatic and autonomic components.

Definition: The peripheral nervous system includes 12 pairs of cranial nerves and 31 pairs of spinal nerves.

Vocabulary: Ganglia - Clusters of neurons that form part of the autonomic nervous system.

Example: The autonomic nervous system has sympathetic (activating) and parasympathetic (calming) components.

Highlight: The peripheral nervous system controls both voluntary and involuntary actions throughout the body.

The Peripheral Nervous System

The peripheral nervous system consists of nerves connecting the central nervous system to the body's various parts.

Definition: Nerves are bundles formed by neuron axons and can be divided into somatic and autonomic systems.

Vocabulary: The somatic nervous system controls voluntary actions, while the autonomic system manages involuntary functions.

Example: There are 12 pairs of cranial nerves serving the head and 31 pairs of spinal nerves reaching the rest of the body.

The Endocrine System

The endocrine system works through specialized glands that release hormones into the bloodstream.

Definition: Hormone production is regulated by the brain through the hypothalamus, which connects to the pituitary gland.

Example: Prolactin is a hormone produced by the female endocrine system after childbirth to enable milk production.

Highlight: Antagonistic hormones like insulin and glucagon work together to regulate blood glucose levels.

Page 1: The Nervous System Structure and Function

The nervous system consists of the central and peripheral components, with neurons serving as the basic functional units. Neurons communicate through specialized structures including dendrites for receiving signals and axons for transmitting them.

Definition: Neurons are specialized cells that process and transmit information through electrical and chemical signals.

Vocabulary: Myelin sheath - A fatty substance that insulates axons and speeds up signal transmission.

Example: There are three main types of neurons: sensory neurons (receive external stimuli), motor neurons (control muscles), and association neurons (process information).

Highlight: The endocrine system works in coordination with the nervous system through the hypothalamus and pituitary gland.
