1. 01 Remember the body’s structural organization Essential Questions • How is the human body organized? • What are the structural components of the body? • How does the body’s structural organization relate to its support and movement? 1. 01 Remember structural organization 2
Organization of the human body: Tissues Composed of: 1. 01 Remember structural organization 3
Organization of the human body: Tissues Types of tissues: • Epithelial tissue • Connective tissue • Muscle tissue • Nervous tissue 1. 01 Remember structural organization 4
Organization of the human body: Tissues Epithelial Tissue protects the body by covering internal and external surfaces, and produces secretions • Skin • covers the outside of the body • Membrane • two thin layers of tissue that join together • cells may secrete a fluid 1. 01 Remember structural organization 5
Organization of the human body: Tissues Epithelial tissues Squamous Cuboidal 1. 01 Remember structural organization Columnar 6
Organization of the human body: Tissues Connective tissue supports and connects organs and tissue • Adipose type of connective tissue that stores fat cells • Cartilage firm, flexible support of the embryonic skeleton and part of the adult skeleton • Tendons white bands of connective tissue attaching skeletal muscle to bone • Ligaments strong, flexible bands of connective tissue that hold bones firmly together at the joints 7
Organization of the human body: Tissues Muscle tissue contracts and moves a body part Cardiac striated, involuntary contracts the heart Skeletal striated, voluntary attached to the skeleton Smooth • nonstriated, involuntary • provides movement in various body systems 1. 01 Remember structural organization 8

Structural organization units Anatomical position: Body is facing forward, standing erect, feet parallel, holding arms at side with palms facing forward. 1. 01 Remember structural organization 27
Structural organization units Anatomical position Discuss the importance of anatomical position. 1. 01 Remember structural organization 28
Structural organization units Directional terms: refer to location of a structure or the relative position of a body part to another one. Anterior/Ventral: front of the body Posterior/Dorsal: back of body 1. 01 Remember structural organization 29
Structural organization units Directional terms Medial: towards middle LATERAL: towards side 1. 01 Remember structural organization 30
Structural organization units Directional terms Superior: refers to head, top or upper body or section terms Directional Inferior: refers to tail, bottom or lower body or section Cranial: refers to the head Caudal: refers to the tail or tailbone 1. 01 Remember structural organization 31
Structural organization units Directional terms SUPERFICIAL: on or near the surface Deep: on the inside Proximal: refers to nearest to the point of insertion Distal: refers to farthest from the point of insertion
Structural organization units Body planes: an imaginary line that divides the body or an organ into sections Sagittal: divides the body into right and left halves (midsagittal means equal halves) Frontal: divides the body into anterior and posterior sections (also known as coronal plane) TRANSVERSE: divides the body into top and bottom sections 1. 01 Remember structural organization 33
Structural organization units Body Cavity Video • https: //www. youtube. com/watch? v=x. L 4 TWO 5 CC 84 (again… just watch)
Structural organization units Body cavities: spaces within the body that contain and protect organs • Cranial and Spinal = Dorsal • Thoracic, Abdominal and Pelvic =Ventral 1. 01 Remember structural organization 35
Structural organization units Body Cavities: DORSAL= • Cranial: contains brain • Spinal: contains spinal cord
Structural organization units Body Cavities: VENTRAL= • Thoracic: contains heart, lungs, bronchi, trachea, esophagus, and thymus gland • Abdominal: contains stomach, liver, gallbladder, pancreas, spleen, intestines, and appendix • Pelvic: contains urinary bladder, reproductive organs and rectum (Abdominopelvic = abdominal + pelvic cavities)
Abdominal Quadrants 1. 01 Remember structural organization 38
Abdominal Regions Middle column. Epigastric: area just below the sternum (breastbone) UMBILICAL: area around the umbilicus (navel) Hypogastric: area below the stomach (pubic area) Side columns. Right and left Hypochondriac: areas below the ribs Right and left Lumbar: area on each side of the umbilicus.
