A&P quiz 1 Flashcards
The basis for communication in anatomy and physiology assumes _____?
Anatomical position
Dorsal Cavities (2)
Cranial and Vertebral
Ventral Cavities (2)
Thoracic and abdominopelvic
Superior and anterior
S: toward the head- I: toward the feet
Proximal and distal
P: closer the sagittal D: farther from sagittal } extremities
Anterior (ventral) and posterior (dorsal)
Ventral: front of body/organ
Dorsal: back of body/organ
Sagittal plane
Divides body in half at the midpoint
Frontal plane
divides body in anterior and posterior
Transverse
divides superior and inferior
Medial and lateral
medial is towards sagittal
Lateral away from sagittal
Separates thoracic and abdominal pelvic cavity
Diaphragm
Pericardium: heart
Visceral: covers the heart
Parietal: covered by fibrous pericardium
Pleura: lungs
Visceral: covers lungs
Parietal: lines cavity walls
Peritoneum: abdominal
Visceral: covers abdominal organs
Parietal: lines cavity walls
Protection: skin, nails, hair
Integumentary
Support and protection: bones, ligaments
Skeletal
Movement: skeletal muscles, tendons
Muscular
Detects change & sensory: brain, spinal cord, nerves
Nervous
Hormones: glands, pancreas, ovaries, testes
Endocrine
Transports: heart, arteries, veins
Cardiovascular
Immune cell production: lymph nodes, spleen
Lymphatic
Gas exchange: pharynx, larynx, lungs
Respiratory
Breakdown and absorption: mouth, stomach, intestines
Digestive
Removes waste and liquid: kidneys, uterus, bladder
Urinary
sperm and egg production, fetal development: penis, vagina, ovaries, testes
Reproductive systems
Protective layer that bounds cells
plasma membrane
power house, center of control
nucleus
surrounds and protects nucleus
nucleus membrane
center of nucleus: contains ribosomal RNA and protein
Nucleolus
Strands of DNA: represents your genetic coding
chromatin and DNA
membrane network attached to ribosomes: protein synthesis cellular transportation
Rough endoplasmic reticulum
membrane network without ribosomes: lipid synthesis and cellular transport
Smooth endoplasmic reticulum
flattened sacs near nucleus: packing glycoproteins for transport and secretion
Golgi Apparatus
double membrane with folded inner membrane: synthesis of ATP
mitochondria
Sacs containing digestive enzyme: destroys cellular debris and worn-out organelles
lysosomes
proteins in cilia, flagellum & centrioles: support and mobility within cells
microtubules cytoskeleton
threads of protein actin: maintain & change cell shape, muscle contraction within cell mobility
micro fibrils cytoskeleton
movement along concentration gradient from high to low
diffusion
diffusion of water molecules across the plasma membrane
osmosis
solution with high solute concentration
hypertonic
solution with low solute concentration
hypotonic
relatively equal number of solute molecules and solvent molecules
isotonic
cells grow, synthesize material needed for S phase
G1 phase
replicates DNA
S phase
completes growth and production of enzymes
G2 phase
chromosomes condense and become visible
spindle apparatus form
centrioles migrate
prophase
chromosomes align along metaphase cell
spindle attach to kinetochores
extend from centrosome
metaphase
spindle fivers pull sister chromatid to opposite poles
each pole has identical set of genes
anaphase
nuclear envelope reassembles
chromosomes re-condense
spindle disappears
divides into 2 cells
telophase
Prophase, metaphase, anaphase, telophase
mitotic phase
G1, S, G2
interphase
