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.
