What osteogenic connective tissue layer lines the marrow/medullary cavity
flexion
What type of motion occurs at the neck when the chin is drawn closer to the sternum
microvilli
Which cell structure is responsible for increase in surface area to permit more absorption?
Macrophages
Which cell type present in the connective tissue proper belongs to both the fixed cells and the wandering cells?
atlas and occipital condyles
Which of the following are bones or bone features that articulate directly with one another at the joint
Spinous process
Which of the following features is present on all vertebra and projects posteriorly forming the bumps that you feel down your spine?
Os coxa or coxal bone
Which of the following is considered part of the pelvic girdle?
melanocytes
Which of the following is involved in the coloring of the skin?
increasing bone length during growth
Which of the following is not a reason why bone remodeling occurs:
anterior, ventral
Which of the following pairs consists of anatomical equivalence?
Shaft
Which of the following parts of the hair is location outside of the body?
the frontal bones forms the lateral portion of the eye orbit
Which of the following statements is false
ellipsoid joint
Which of the following synovial joint is a biaxial joint?
The stratum basale is composed of a single cell layer that is attached to the basal lamina and contains stem cells
Which statement is correct about the layers of the epithelium?
Halocrine
Which term defines the mode of secretion involving the rupturing of the cell membrane causing cell death?
Epithelial tissue
a sheet of cells that covers an exposed surface or lines an internal cavity or passageway. Includes tissue and glands that excrete mucus
Transitional epithelia
found in bladder. can be two shapes: squamous and cuboidal. Squamous when bladder is full, and cuboidal when bladder is empty. Permits expansion and recoil.
Simple cuboidal epithelia
found in glands and ducts
Stratified cuboidal
found in the lining of some ducts (rare)
Stratified columnar
found in the salivary gland duct.
Simple columnar
found in the stomach. one layer that is thicker, provides protection from the stomach acids
Mode of secretions
merocrine, apocrine, and halocrine (simplest to most complex). Merocrine releases secretions to the surface. Apocrine will release the apical portion of the cell, nuclei is still intact. Halocrine: cell division replaces lost cells, cells produce secretions increasing in size, and eventually burst releasing cytoplasmic content.
lateral rotation the humerus at the shoulder
moving the arm in the transverse plane so that the medial aspect is now on the lateral side
Stratified squamous
offer protection. found on the skin, mouth, throat, vagina
Functions of epithelial tissue
provide protection, control permeability, provide sensation, produce secretions
Classification of epithelia
simple, stratified. simple squamous, stratified squamous,
irregular
A verterbra is an example of what type of bone
Pseudostratified ciliated columnar
Actually has one layer but it appears to have more than one. Found in the respiratory system.
they start to die
As cells are pushed from deeper layers of the epidermis towards the surface:
lumbar hyperlordosis; anterior
Bob is an overweight patient with an excessively large beer belly.
Characteristics of epithelia
Cellularity (cells bounded closely together), polarity (uneven distribution of organelles towards the bottoms), attachment (all epithelial are attached to a basal lamina), avascularity (no blood vessels), arranged into sheets/layers, regeneration (stem cells)
Simple squamous
Don't offer much protection. the lining of heart and blood vessels
epiphyseal plate
In younger individuals who are still growing, the diaphysis and epiphysis are separated by:
Upper left
Most of the stomach is located in which quadrant:
cartilaginous amphiarthrosis

hinge joint
the joints between phalanges are example of a
manubrium
the sternal end of the clavicle articulates with the
Glandular epithelia
two types: exocrine, and endocrine. Exocrine release secretion to the surface. Endocrine discharge their secretions to the interstitial fluid.
radial head; radial notch
what are the bone features that allow supination/pronation?
greater trochanter
which bone feature is a muscle attachment site that would attach with a muscle involved with movement at the hip joint
reducing friction in a tendon
which of the following is not a function of synovial fluid
