Study Notes
Overview of Anatomy
- Anatomy is the branch of biology focused on the structure of organisms.
- It is divided into several sub-disciplines, including:
- Gross Anatomy: Study of structures visible to the naked eye.
- Microscopic Anatomy: Study of structures at the cellular level, including histology and cytology.
- Developmental Anatomy: Study of growth and development from conception to maturity.
Major Divisions of Human Anatomy
-
Skeletal System
- Comprised of bones, cartilage, and ligaments.
- Functions: support, protection, movement, mineral storage, and blood cell production.
-
Muscular System
- Comprises muscles, tendons, and fascia.
- Functions: movement, stability, posture, and heat production.
-
Circulatory System
- Includes the heart, blood vessels, and blood.
- Functions: transport of nutrients, gases, hormones, and waste products.
-
Respiratory System
- Composed of the lungs, trachea, and diaphragm.
- Functions: gas exchange, oxygen intake, and removal of carbon dioxide.
-
Digestive System
- Includes organs such as the mouth, esophagus, stomach, intestines, liver, and pancreas.
- Functions: digestion, nutrient absorption, and waste elimination.
-
Nervous System
- Comprises the brain, spinal cord, and nerves.
- Functions: control and coordination of body functions through electrical signals.
-
Endocrine System
- Composed of glands such as the pituitary, thyroid, and adrenal glands.
- Functions: regulation of body processes through hormones.
-
Urinary System
- Includes the kidneys, ureters, bladder, and urethra.
- Functions: filtration of blood, waste excretion, and regulation of fluid balance.
-
Reproductive System
- Comprises male (testes, penis) and female (ovaries, uterus) reproductive organs.
- Functions: production of gametes and hormones, continuation of species.
Anatomical Terminology
- Anterior (ventral): front
- Posterior (dorsal): back
- Superior (cranial): above
- Inferior (caudal): below
- Medial: closer to the midline
- Lateral: farther from the midline
- Proximal: closer to the point of attachment
- Distal: farther from the point of attachment
Body Planes and Sections
- Sagittal Plane: divides the body into left and right halves.
- Coronal (frontal) Plane: divides the body into anterior and posterior parts.
- Transverse (horizontal) Plane: divides the body into superior and inferior parts.
Histology (Microscopic Anatomy)
- Tissues are categorized into four primary types:
- Epithelial Tissue: covers body surfaces, lines cavities, and forms glands.
- Connective Tissue: supports and binds other tissues; includes bone, blood, fat, etc.
- Muscle Tissue: responsible for movement; includes skeletal, cardiac, and smooth muscle.
- Nervous Tissue: makes up the brain, spinal cord, and nerves; involved in signal transmission.
Developmental Anatomy
- Embryology: study of development from fertilization to birth.
- Key stages: zygote, blastocyst, embryo, and fetus.
- Importance of understanding developmental milestones and congenital conditions.
Techniques in Anatomy
- Dissection: method of studying anatomy by cutting and separating tissues.
- Imaging Techniques: X-rays, MRI, CT scans, and ultrasound for visualizing structures non-invasively.
- Histological Techniques: preparation of tissue samples for microscopic examination.
Anatomy Overview
- Anatomy is the study of the structure of organisms.
- It covers a wide range of topics, including:
- Gross Anatomy: Studying structures visible without a microscope.
- Microscopic Anatomy: Studying structures at the cellular level, including histology (tissues) and cytology (cells).
- Developmental Anatomy: Studying the growth and development from conception to maturity.

Anatomical Terminology
- Anterior (ventral): towards the front of the body.
- Posterior (dorsal): towards the back of the body.
- Superior (cranial): above or towards the head.
- Inferior (caudal): below or towards the tailbone.
- Medial: closer to the midline of the body.
- Lateral: further from the midline of the body.
- Proximal: closer to the point of attachment.
- Distal: further from the point of attachment.
Body Planes and Sections
- Sagittal Plane: divides the body vertically into left and right halves.
- Coronal (frontal) Plane: divides the body vertically into anterior and posterior parts.
- Transverse (horizontal) Plane: divides the body horizontally into superior and inferior parts.
Histology (Microscopic Anatomy)
