Study Notes
Nervous System and Its Functions
- The primary function of the nervous system is to transmit signals between different parts of the body, allowing for communication and coordination of actions.
- It plays a crucial role in processing sensory information, controlling motor functions, and maintaining homeostasis.
Coordination and Balance
- The cerebellum, located at the back of the brain, is responsible for coordination and balance, enabling smooth and precise movements.
Endocrine System's Role
- The endocrine system complements the nervous system in coordination by secreting hormones that regulate various physiological processes, including growth, metabolism, and response to stress.
- Hormones act as chemical messengers, influencing activities in distant organs and tissues.
Characteristics of Metals
- Metals are typically characterized by their ability to conduct electricity and heat, malleability, ductility, and high density.
- They usually have a shiny appearance and are solid at room temperature, except for mercury.
Properties of Non-Metals
- A common property of non-metals is their poor conductivity of heat and electricity, often resulting in them being insulators.
- Non-metals are usually brittle in solid form and can exist in different states: gases (like oxygen), liquids (like bromine), or solids (like sulfur).
Formation of Positive Ions
- Elements located on the left side of the periodic table, predominantly metals, are likely to form positive ions (cations) by losing electrons during chemical reactions.
