Study Notes
Organ Systems and Anatomy
- The study of anatomy focuses on the structure, shape, and relationship of body parts.
- Anatomy is categorized into Gross Anatomy (visible structures) and Microscopic Anatomy (study of cells and tissues).
- Functional Anatomy examines how structure relates to function within the body.
Basic Elements of Humans
- Human organisms are primarily composed of four elements: carbon, hydrogen, nitrogen, oxygen.
- Human body is approximately 60-70% fluid.
Neuroanatomy
- Neuroanatomy studies the structure and function of the nervous system, emphasizing the relationship between structure and behavior.
- Neurotransmitters function at the molecular/chemical level, while neurons are the basic nerve cells at the cellular level.
- Ganglia refer to clusters of nerve cell bodies, and nuclei are groups of neurons with similar functions.
Functional and Clinical Neuroanatomy
- Functional Neuroanatomy addresses the operations of different neuroanatomical parts and their role in behavior.
- Clinical Neuroanatomy relates to diseases and disorders affecting the nervous system.
Structural Organization of the Human Body
- Cells are the smallest functional units and consist of combinations of atoms and molecules.
- Tissues combine cells to perform specific functions.
- Organs are composed of tissues working together to fulfill a specific function.
Nervous System Organization
- The nervous system is divided into the Central Nervous System (CNS) and Peripheral Nervous System (PNS).
- The autonomic nervous system is further categorized into the sympathetic and parasympathetic systems.
- The somatic nervous system controls voluntary movements, while the autonomic system regulates involuntary functions.
Key Neuroanatomical Structures
- Essential brain structures include:
- Hippocampus: involved in memory formation.
- Hypothalamus: regulates various homeostatic functions.
- Amygdala: plays a role in emotion and behavior.
- Cerebrum: responsible for higher functions including thought and action.
- Cerebellum: coordinates movement and balance.
- Brain stem: controls basic life functions.
Systems Overview
- The limbic system influences emotions and memory.
- Basal ganglia are associated with movement regulation.

- Origin: Medulla oblongata
- Function:
-
Cranial Nerve XI: Accessory
- Function: Motor for shoulder shrug and head turning
- Origin: Medulla oblongata; involves spinal components
-
Cranial Nerve XII: Hypoglossal
- Function: Motor for tongue movement
- Origin: Medulla oblongata
