co-ordination Flashcards
what is neuromuscular junction
synaptic connection between end of motor nerve and a muscle
types of neurons
sensory motor associated nerves
types of actions
voluantry invountary reflex action
what is reflex arc
(neural pathway that transmits the actions in the body) a single pathway that goes upto the spinal cord from receptors and return in effector muscle/organ
what are the componenets of reflex arc
5:-
receptor
sensory nerve
associated nerve
motor nerve effector organ
brain is protected by membrane and fluid called
membrane- meninges
fluid- cerebro- spinal fluid
fore brain is divided into
two parts:-
cerebrum
diencephalon—- thalamus
hypothalamus
lobes in cerebrum
frontal lobe, perital lobe, temporal lobe, optical/occipital lobe
hind brain consists of
cerebellum, medula oblongata ,pons
name some receptors
photo
phono
gustatory
olfactory
thermo
name 6 endocrine glands and their hormones
pitrutary gland– somatotrophin, vasopressin, thyrotropin, gonadotropin etc
thyroid gland– thyroxine
ovary — estrogen, progesteron (during
pregnency)
testes— testesterone
adrenal– adrenaline
pancrease– insulin glycogen
name the types of movement in plants
nastic movement- not related to growth
trophic movement- realted to growth
name types of tropic movement
phototropism–positive tropisim
geotropism-positive/negetive
chemotropism-positive/negetive
hydrotropism- positive/negetive
thigmotropism- the directional growth of the plant towards thetouch of an object/stimulus
name the 5 plant hormones
auxins
cytokinins
gibberellins
abscisic acid
ethylene
types of nastic movemnt
thigmonastic
photonastic
scientific name of touch me not plant
mimosa pudica
who discovered auxins
FW went
what is symphetic and parasymphetic nervous system
symphetic- activates when our body is in an alert situation
parasyphetic- helps to deactiviate and regulate symphetic NS– turning things back to normal
they work with each other/ balance/ first symphetic NS takes the domination to get through the alert situation and parasymphetic NS normalises the condition
what are islets of langerhands
cell in pancrease that releases hormones glycogen and insulin
what are gyri and sulci
a gyri are rigid like projection present on the cortex of the brain and surrounded by depressions called as sulci
they together form the iconic surface of the brain
who introducted the term hormone
ernest starling
who identified nerve corodination
gallen
