How many bones in skull?28 (14 facial, 14 cranial) How many bones in verterbral column? 33 How many phalanges?56 How many pairs of ribs?12 Abdominopelvic Cavity composed of the abdomen and pelvis Absorption Movement of nutrients from the digestive tube to the bloodstream ActinProtein making up the I Band of the sarcomere Amino Acid The building block of proteins Antibody Special proteins that protect the body from foreign substances ATPAbbreviation for Adenosine triphosphate, which is the energy of the cell. In muscles, this energy causes filaments to slide together to produce contraction.AtriaUpper chambers of the heart; receives blood 2 / 4
BloodConsists of approximately 55% plasma and 45% formed elements (erythrocytes, leukocytes, and platelets). Serves to transport oxygen and nutrients to body cells and to carry away carbon dioxide and metabolic wastes Plasma Contains about 10% proteins, ions, nutrients, waste products, and hormones, which are dissolved or suspended in water.Formed Element Erythrocytes, leukocytes, and platelets; produced from stem cells in red bone marrow.Tricuspid Valve Valve on the right side of the heart between the atrium and ventricle Bicuspid Valve Valve on the left side of the heart between the atrium and ventricle Semilunar Valve Found at the entrances of the pulmonary trunk and the aorta.Sinoatrial Node Initiates the heart's intrinsic beat ElectrocardiogramMeasurement of the wave of electrical activity within the heart Systole Contraction phase of the cardiac cycle Diastole Relaxation phase of the cardiac cycle Muscle ContractionResults in the sliding together of actin and myosin filaments within the muscle cell or fiber Mitosis Necessary for growth and repair. The DNA is duplicated and distributed to 2 daughter cells.Meiosis Special cell division that takes place in the gonads. Chromosome number is reduced from 46 to 23 so wen the egg and the sperm unite in fertilization the zygote will have the correct number of chromosomes.SkinThe largest organ in the body. Consists of the epidermis and the dermis.Epidermis Outer, most protective layer of dead keratinized epithelial cells. Contain Melanin.Stratum corneum - stratum lucidum - stratum granulosum - stratum germinativum (outer layer to inner).Dermis Underlying layer composed of fibrous connective tissue with blood vessels, nerve 3 / 4
endings, and the associated skin structures (hair follicles/glands) Melanin Protein pigment that protects against radiation from the sun Eccrine Gland Most widely distributed sweat glands that regulate body temperature by releasing a watery secretion that evaporates from the surface of the skin Apocrine Gland Sweat gland that produce a secretion containing cytoplasm. Mainly found in the armpit and groin areas.Sebaceous Gland Release an oily secretion through the hair follicles that lubricates the skin and prevents drying. These glands are susceptible to becoming clogged and attracting bacteria, particularly during adolescence.Holocrine SecretionProduces oil; whole cells of the sebaceous gland are part of this secretion Skeletal System Functions to support, permit movement, form blood cells (homeopoiesis), protect internal organs, detoxify, point for muscle attachment, mineral storage (particularly phosphorous and calcium) Long Bone Has an irregular epiphysis at each end, composed mainly of spongy (cancellous) bone. Has a shaft (diaphysis) composed of compact bone.Osteoblast Form compact bone; Once becoming fixed into the bone matrix, they stop dividing but continue to maintain bone tissue as osteocytes Diaphysis The shaft composed of compact bone Epiphysis End of each bone Axial Skeleton Composed of 28 bones of the skull (14 facial bones and 14 bones of the cranium) and 33 bones of the vertebral column (7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 sacral vertebrae, and the coccygeal vertebrae) and the bones of the thorx, the sternum and the 12 pairs of ribs Appendicular Skeleton Includes the girdles and the limbs. Upper pectoral girdle, the clavicle and the scapula, and the upper extremity, and the bones are the arm and hand. Pelvic Girdle or os coxae, leg, and foot bones.ActinCauses muscle contraction by sliding together with myosin filaments.
