Cards

Term
Epithelial Tissue
Definition
body surfaces(skin), cavities, organs, and glands
Term
Connective Tissue
Definition
protection, support, fat
Term
Muscle Tissue
Definition
skeletal muscle, cardiac muscle, smooth muscle
Term
Membranous (Epithelial Tissue)
Definition
outer layer of skin, lining of digestive system and blood vessels
Term
Glandular (Epithelial Tissue)
Definition
secretes something; exocrine or endocrine
Term
Simple Squamous (Epithelial Tissue)
Definition
single layer flat; air sacs of lungs, heart and blood vessel linings; allows nutrient exchange
Term
Stratified Squamous (Epithelial Tissue)
Definition
multilayer flat; located on surface of skin, lining of mouth, esophagus, and vagina; provides protection against infection and drying.
Term
Simple Cuboidal (Epithelial Tissue)
Definition
single layer cube shape; located in linings of kidney tubules and glands; functions in absorption and secretion
Term
Stratified Cuboidal (Epithelial Tissue)
Definition
multilayer cube; located in ducts of mammary glands, sweat glands, and salivary glands; protection
Term
Simple Columnar (Epithelial Tissue)
Definition
single layer of tall slender cells; located in lining of gut and respiratory tract; functions in absorption and secretion
Term
Stratified Columnar (Epithelial Tissue)
Definition
multilayer tall slender cells; rare, located in urethra (pee track); functions in protection and secretion
Term
Areolar Connective Tissue (Loose Connective Tissue)
Definition
"universal packing tissue" widely distributed, found under skin, around organs, between muscles; wraps and cushions organs
Term
Adipose Tissue (Loose Connective Tissue)
Definition
(Fat) found under skin, around kidneys and heart; functions in energy storage and insulation and cushioning for organs
Term
Dense Connective Tissue
Definition
found in tendons and ligaments; forms strong bands that attach bone to muscle or bone to bone
Term
Cartilage (Special Connective Tissue)
Definition
found in rings of respiratory air tubes, external ear, tip of nose; provides flexible support and cushion
Term
Bone (Special Connective Tissue)
Definition
found in the skeleton; functions in support, protection, and movement
Term
Blood (Special Connective Tissue)
Definition
found within blood vessels; transports nutrients, gases, hormones, wastes, and fights infections
Term
Skeletal Muscle
Definition
many nuclei, long cylindrical cells, voluntary control, most connected to bones
Term
Cardiac Muscle
Definition
one nucleus, striated, long branched cells, involuntary control, found in walls of heart
Term
Smooth Muscle
Definition
one nucleus, tapered shaped cells, involuntary control, most in walls of hollow organs
Term
Peristalsis
Definition
contraction and relaxation of muscles which propagates in a wave down the muscular tube
Term
A follicle with sebum
Definition
canal becomes clogged with sebum, dead cells, and bacteria
Term
Whitehead
Definition
sebum, cells, and bacteria accumulate in the follicle
Term
Blackhead
Definition
sebum in the clogged follicle mixes with melanin (pigment)
Term
Inflamed Pimple
Definition
follicle wall ruptures, releasing the contents of a white/blackhead into the surrounding epidermis
Term
Osteon
Definition
functional unit of compact bone
Term
Osteoblast
Definition
cells that make other bone cells and mineralize (ossify) them
Term
Fibrous Joints
Definition
ex: suture joint on top of skull; connective tissue, almost no movement
Term
Cartilaginous Joints
Definition
ex: ribcage; attach bones together, limited to no movement
Term
Synovial Joints
Definition
ex: knee cap; allow movement of appendages
Term
Tendons
Definition
connect muscles to bones
Term
Flexion
Definition
motion that decreases the angle, bone coming together (knee bent towards back)
Term
Extension
Definition
motion that increases the angle between the bones of the joint (knee extended forward)
Term
Adduction
Definition
movement of body part towards the body midline
Term
Abduction
Definition
movement of a body part away from the body midline
Term
Rotation
Definition
movement of a body part around its own axis
Term
Circumduction
Definition
movement of a body part in a wide circle (cone shape)
Term
Anterior-Posterior (Ventral-Dorsal)
Definition
body front - back of body
Term
Superior-Inferior
Definition
towards head - towards legs
Term
Medial-Lateral
Definition
towards midline - away from midline
Term
Proximal-Distal
Definition
close to - away from
Term
Cranial-Caudal
Definition
head end-tail end
Term
Sarcomeres
Definition
functional unit of muscle
Term
Sprain
Definition
injury involving the stretching or tearing of a ligament (bone to bone)
Term
Strain
Definition
injuries that involve the stretching or tearing of a tendon (muscle and tendon)
Term
Tendonitis
Definition
overuse of a muscle-tendon connection
