INTRO TO ZOOT 1100 Flashcards
has a spiny appearance because of its desmosomes (intercellular bridges) connecting adjacent cells.
Stratum spinosum
a local increase in thickness in response to continuous trauma.
callus
Study of the morphological characteristics and
structure of tissues and organs as they relate to surgical diagnosis, treatment and dissection; and anatomical art or the use of dissection techniques in the study of the structures of the parts of the body.
Surgical Anatomy
the drying and hardening
of the superficial cells; renders the surface of the skin tough
and resistant to drying. Rate at which this occurs can be influenced by trauma or disease processes.
Keratinization and cornification
in the distal part of the limb, _____ structures lies toward the rear (hindlimb)
plantar
superficial fascia, subcutis; consists primarily of loose connective tissue and lobules of fat; contains larger blood vessels and nerves than those found in the dermis
hypodermis
receptors responsible for sensing pressure
ruffini endings and pascinian corpuscles
Hornlike growths on the medial sides of horses’ limbs
chestnuts
thin, waxy layer that covers the outside of the hoof
periople
structures that lie toward the junction with the body
proximal
name the 4 receptors that is responsible for feeling touch
Meissner corpuscles, Merkel disks, Krause end bulbs, root hair plexus
consists of layers of dead, flattened cells
stratum corneum
outer layer of the skin
epidermis
surrounded by a scaly cortex, outside of which is a thin cuticle.
medulla
also called corium, consist of dense irregular connective tissues and cushions the body from stress and strain; contains mechanoreceptors and thermoreceptors, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels, nerves, and blood vessels.
dermis
Epidermal growths that form the distinctive outer covering, or plumage.
feathers
structures toward the muzzle
rostrum/rostral
long stiff hairs with specialized innervation that renders them effective as organs of touch.
tactile hair
which among the following shows the correct order of Vit D3 conversion:
A. 7-Dehydrocholesterol - Cholecalciferol - Calcidiol - Calcitriol
B. Cholecalciferol - Calcitriol - 7-Dehydrocholesterol - Calcidiol
C. Calcidiol - 7-Dehydrocholesterol - Calcitriol - Cholecalciferol
A.
in the proximal of part of the limb, the structures that lie toward the front are called_____
cranial
this pertains to the structures or positions that lie towards the back
dorsal
base of the follicle where living cells divide and grow to build the shaft.
hair bulb
structures that lie toward the side
lateral
type of hair which form the smooth outer coat
guard hair
Study of anatomy at the visible or macroscopic level, in short, used of the naked eye
Gross Anatomy
classified as holocrine glands because their oily secretory product, sebum, is produced by disintegration of epithelial cells within the glands.
sebaceous glands
