Week 3-Organization of the body Flashcards
Anterior
Front side of body
Anabolism
Process of building up large protein from small protein pieces (amino acids)
Cell membrane
Structure surrounding and protecting the cell
Chromosomes
Rod-shaped structures in the nucleus that contains regions of DNA (genes)
Catabolism
Process whereby complex nutrients are broken down to simpler substances and energy is released
Deep
Away from the surface
Distal
Far from the point of attachment to the trunk or near the beginning of a structure
Genes
Regions of DNA within each chromosome
DNA
Chemical found within each chromosome; Directs the activities of the cell
Inferior
Below another structure
Lateral
Pertaining to side
Mitochondria
Structures in the cytoplasm that provide the principal source of energy of the cell
Medial
Pertaining to the middle, or nearer the medial plane of the body
Posterior
Back side of body
Cartilage
Flexible connective tissue attached to bones at joints
Epithelial cells
Skin cells that cover the outside of the body and line the internal surfaces of organs
Prone
Lying on belly
Larynx
“Voice box;” Located at the upper part of the trachea
Pharynx
Throat; Common passageway for food and air
Proximal
Near the point of attachment to the trunk or near the beginning of a structure
Trachea
“Windpipe;” Tube leading from the throat to the bronchial tubes
Ureter
One of two tubes, each leading from a single kidney to the urinary bladder
Urethra
Tube from the urinary bladder to the outside of the body
Uterus
Womb; organ that holds the embryo/fetus as it develops
Viscera
Internal organs
Abdominal cavity
Space below the chest containing organs such as the liver, stomach, gallbladder, and intestines
Cranial cavity
Space in the head containing the brain and surrounded by the skull
Diaphragm
Muscle separating the abdominal and thoracic cavities; Moves up and down and aids in breathing
Dorsal
Posterior; back surface of the body
Mediastinum
Centrally located space outside of and between the lungs
Pelvic cavity
Space below the abdomen containing portions of the intestines, rectum, urinary bladder, and reproductive organs
Peritoneum
Double-folded membrane surrounding the abdominal cavity
Pleura
Double-folded membrane surrounding each lung
Pleural cavity
Space between the pleural layers
Spinal cavity
Space within the spinal column containing the spinal cord
Thoracic cavity
Space in the chest containing the hear, lungs, bronchial tubes, trachea, esophagus, and other organs
Ventral
Anterior; pertaining to the front
Hypochondriac
Right and left upper regions beneath the ribs
Epigastric
Middle region above the stomach
Sagittal plane
Lateral plane; lengthwise vertical plane dividing the body or structure into right and left sides
Umbilical
Central region near the navel
Hypogastric
Middle lower region below the umbilical region
Inguinal
Right and left lower regions near the groin
Cervical
Neck region (C1 to C7)
Thoracic
Chest region (T1 to T12)
Thyroid gland
Endocrine gland that surrounds the trachea in the neck
Coccygeal
Region of the coccyx (tailbone); 4 fused pieces
Vertebra
Single backbone
Frontal plane
Coronal plane; vertical plane dividing the body/structure into anterior and posterior portions
Transverse plane
Axial plane; horizontal (cross section) plane running across the body parallel to the ground
