Study Notes
Systematic Anatomy Nomenclature
- Osteology: Study of bones; focuses on skeletal structures.
- Arthrology: Study of joints; includes all types of joint structures.
- Myology: Study of muscles; covers muscular anatomy.
- Splanchnology: Study of organs; encompasses digestive, respiratory, and urinary systems.
- Endocrinology: Study of ductless glands; involves hormonal systems.
- Neurology: Study of the nervous system; includes the brain, spinal cord, and nerves.
- Angiology: Study of the circulatory system; focuses on the heart and blood vessels.
- Dermatology: Study of the skin; explores integumentary structures.
- Esthesiology: Study of sensory organs; relates to the eyes and ears.
The Skeletal System
- Composed of bones providing framework, support, protection, and storage.
- Functions: Supports body structure, muscle attachment, aids locomotion, manufactures red blood cells, stores minerals.
Bone Structure
- Compact Bone: Dense layer covering most bones, forming the shaft of long bones.
- Cancellous (Spongy) Bone: Porous structure found within bones, houses marrow.
- Diaphysis: The shaft of a long bone; primarily composed of compact bone.
- Epiphysis: The ends of a long bone; includes spongy bone and overlying hyaline cartilage.
Bone Growth and Development
- Epiphyseal Plate: Hyaline cartilage layer that allows lengthwise growth of long bones, replaced by bone after puberty.
- Endosteum: Membrane lining the marrow cavity, involved in bone health.
Classification of Bones
- Long Bones: Cylindrical with a shaft (diaphysis) and two ends (epiphysis); e.g., humerus and femur.
- Short Bones: Cube-like with no marrow cavity; e.g., tarsus and carpus.
- Flat Bones: Thin and expanded; protect organs and provide muscle attachment; e.g., scapula.
- Sesamoid Bones: Develop within tendons, reduce friction; e.g., patella.
- Irregular Bones: Unique shapes, support and protect; e.g., vertebrae.
Joint Classification
- Diarthrosis: Freely movable joints; characterized by a cavity, capsule, and articular surfaces.
- Types of Diarthrodial Joints:
- Ginglymus (hinge): Movement in one plane; e.g., fetlock joint.
- Arthrodial: Slight gliding movement; e.g., carpal joints.
- Trochoid (pivot): Rotary movement around one axis; e.g., atlanto-axial joint.
- Enarthrodial (ball and socket): Movement in multiple directions; e.g., hip joint.
Types of Gaits
- Plantigrade: Entire foot contacts the ground; e.g., humans and bears.
- Digitigrade: Digits touch ground, rest elevated; e.g., cats and dogs.
- Unguligrade: Tips of digits (hooves) touch ground; e.g., cows and pigs.
Bone Fractures
- Comminuted: Bone shatters into multiple pieces; common in older individuals.
- Compression: Bone is crushed; seen in porous bones.
- Depressed: Bone pushed inward; often occurs in skull fractures.
- Impacted: Broken ends forced together; happens when falling.
- Spiral: Ragged break due to twisting forces; common in sports injuries.
- Greenstick: Incomplete break; typical in younger animals due to flexible bones.
Interesting Facts
- Thigh bone (femur) is the longest bone; ear bones (malleus, incus, stapes) are the smallest.
- Hyoid bone: A floating bone resistant to fractures; indicators of strangulation if broken.
- Newborns possess approximately 300 bones, which fuse to form 206 in adulthood.
