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

|
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
|
