Anatomy Unit Unit Meiosis Mitosis
Unit 5 & 6
Meiosis consists of __ cell divisions with __ phases which are:
Prophase I, Metaphase I, Anaphase I, Telophase I
Prophase II, Metaphase II, Anaphase II, Telophase II
Mitosis creates __ ______ daughter cells
______ to the parent cell.
Meiosis creates __ _____ daughter cells ______ to the parent cell.
allows for a variation. Chromosomes touch each other to allow for genetic diversity. Occurs in Prophase 1.
Purpose of Meiosis
to cut chromosome number in half. Happens in metaphase or anaphase 1. 1 splits chromosomes, 2 splits chromatids. Sex cells
different forms of the same genes. Dominant and recessive forms. Dominant gets expressed if present.
collection of genes.
genes that get expressed
has one dominant and one recessive
determine genotypic and phenotypic ratios.
Sex linked disease:
hemophilia and color blindness. Usually carried on X, which makes males more vulnerable.
not a sex linked chromosome.
change in DNA. Nucleotide sequence gets changed. Caused by radiation,
viruses, chemicals, replication errors. Mutating DNA can cause medical
disorders because it makes the wrong protein which isn't what your body
homologous chromosomes didn't split which results in trisomy or monosomy. not normal.

missing a chromosome
Down Syndrome: Most survivable
has no pigment because no melanin
Sickle cell anemia :
red blood cells are sickle shaped and clump and clot, autosomal recessive disease.
is also autosomal recessive disease that you cannot process phenoalonen?
Albinism, Sickle cell anemia, PKU
for support, movement, protection, blood cell production, mineral reservoir
thermoregulation, sensation, vitamin D,
Red bone marrow
where blood cells are made, mainly in children
Yellow Bone Marrow
mainly in adults, made of fat
is flaired end of long bone
is shaft of long bone
inside/middle of long bone
Covering around outside bone
on ends of long bone
on spongy bone to increase strength of bone without increasing weight.
flat bones of skull.
build bones, blood CA decreases,
destroy bone, blood CA increases.
lowers blood CA by stimulating osteoblast
increases blood CA by stimulating osteoclast
4 types of membrane:
is passageways to outside world
Produce sebum (oil)
open into a hair follicle
Ducts open into hair follicles instead of skin surface
made of epithelial cells, keratinocytes
Deep layer of Epidermis
Middle layer of Epidermis
Outer layer of Epidermis
basic structural unit of compact bone
childhood disease, not enough vitamin D/ calcium. Bones bow and deform
adult form of Rickets
Osteoclast outdo osteoblast
types of joints:
fluid filled sac between tendon and bone
Connective tissue that connects bone to bone
Connective tissue that connects muscle to bone:
torn ligament or tendon
stretched ligament or tendon
chronic wear and tear
ball and socket
ball and socket:
elbow or knee.
radial carpal or metacarpal phalangeal.
base of thumb, trapezealmetacarpal.
carpal bones, articular process of vertebrae
