46 Cards in this Set

  • Front
  • Back
Nuclear Membrane
separates cytoplasm from neoplasm; pores allow passage
chromatin
genetic material; becomes chromosomes during cell division
Necleousis
forms ribosomes
mitrochrondria
powerhouse; atp synthesis converts energy from nutrients into useable product for body
Ribosomes
protein synthesis
endoplasmi reticulum
transports material through cytoplasm
rough reticulum=protein; smooth reticulum=lypid synthesis
Plasma membrane
maintains integrity of the cell; controls passage of material
cytoplasm
medium for chemical reaction; suspending medium for organelles
nucleus
contains genetic material; regulates activities of cell
gogli apparatus
packages products for secretion from lyosomes
lyosomes
digests materials taken into cell; debris from damaged cells
cytoskeleton
provides support for cytoplasm; helps movement of organelles
centrioles
distributes chromosomes to daughter cells during cell division
cilia
moves substances across surface of cell
flagella
cell locomotion
Layers of meninges
dura (outside)
arachnoid (middle)
pia (inside)
cerebellum function
2nd largest section
below occipital lobes
motor area; coordinates skeletal and muscle activity
hypothalmus function
maintains homeostasis;regulates many visceral activities
body temp,
food intake,
thirst/water balance,
sleep/wake cycles,
endocrine system activities,
emotional response & behavior,
regulates and integrates autonomic nervous system
Medulla Function
5 pair of cranial nerves
cardiac center (heart rate and cont. strength)
vasomotor (b/p)
respiration (rate, rhythm, depth of breath)
Chroid Plexus
4 cavities called ventricles contain CSF
CSF is formed from the blood in the chorid plexus of ventricles, circulates through ventricles and subarachnoid space then returns to blood in the dural sinuses.
Larynx
9 cartilages make up larynx (voice box)
ALl are hyaline cartalige except epiglottis which is elastic cart.
Pairs of cart...arythenoid, corniculate, cunciform.
Singles thyroid (adams apple) cricoid (base of attachement) epiglottis (moveable flap)
Plura of Lungs
Parietial Plura -lines the wall of thorax
VIsceral Pleura -attached to surface of lungs
plural cavity- space between parietial and visceral
Muscles for breathing
quiet breathing muscle - diaphram
laboured breathing muscles- external intercostal muscles
Interneurons or associate neurons
located within CNS connecting link between afferent and efferent neurons.
Types of Nurons
afferent

efferent
Afferent neuron (sensory)
carries impulses from peripheal sense receptors to SNS. Long dendrites and short axons.

Efferent neuron (motor) transmits impulses from CNS t oeffector organs such as muscles and glands. short dendrites , long axons
SHort bone
cube shaped
promarily spongy bone covered by thin layer of compact bone. wrist, ankel
bone coverings

periosteum

endosteum
Periosteum - tough fibrous tissue on outside of bone

endosteum - contains osteoclasts
Long Bone
shaft diaphysis
epiphysis - expanded portion at ends

diaphysis -compact bone
epiphysis - spongy bone covered in compact bone, covered with hyaline cart

thigh, forearm
Epiphyseal plate

epiphyseal line
plate-of hyaline cart, bone grows here

line-forms when bone growth stops
function of keratin
provides skin color
function of cebum
keeps skin soft and pliable
inhibits bacterial growth
prevents water loss
Nervous tissue
brain, spinal cord, nerves
muscular tissue
actin and myosin are contractile proteins in muscular tissue
connective tissue
abundance of intercellular matrix with relatively few cells

most common connective tissue
fibroblasts, mactophages and mast cells
4 main tissue types
epithelial
connective
muscular
nervous
function of reproductive system

blood cell formation
function of muscular system
movement
posture
joint stability
heat production
Function of urinary system
rids body of waste materials
regulates fluid volume
maintains electrolyte concentrations
controls blood ph
secretes erythropoietin & renin
function of digestive system
digestion
absorption
metabolism
functions of integumentary system
protection
sensory reception
regulates body temp
synthesis of vit D
Functions of endocrine system
secretes hormones
function of blood
transports
regulates
