Locomotion And Movement Flashcards
A: every locomotion is movement but every movement is not locomotion
R: movent occur in any organ or cell structure or organism
Correct explanation
Displacement of WBC is
Movement because it is not an organism
Locomotion structure need not be different from sturture use for movement in
Hydra as hydra use tentacle for movement and locomotion also for (food )
Exception of locomotion is

Each organised skeletal muscles in our body is made up of number of fascia held together by a common collagenous connective tissue layer called muscles fiber or fascicles
Wrong
Each organised skeletal muscles in our body is made up of number of muscles fiber or fascicles
By a common collagenous connective tissue layer called fascia
Some muscle bundle contains a number of muscles fibers
Wrong
Each muscles bundle contains number of muscles fibers
Muscle bundle held together by a common collagenous connective tissue layer called fascia MEANS
It is say it is epimysium and epimysium,endomysium, perimysium are arise from fascia
Muscles fiber are lined by plasma membrane called
Sacrolemma enclosing the sacroplasm
Chemical compound undergose ___'’types of change
Twophydical and chemical
Hydrolysis of strach into glucose is an inorganic chemical reaction
False organic
Thin and thick filament are ________
Actin and myosin are thin and thick resp.
In the center of each ___ bandis an elastic fiber called ___ line
- I
- Z
The thin filament are weakly attached to z line
Firmly = strongly
The thick filament in the __ band is also held together in the ___ of this band bya thin membraneous fiber called
- A
2.middle
3.M line
Sarcomere is
The portion of myofibrils between two successive Z line
It is the functional unit of contraction
Bright portion is
The portion in which only myosin filament is present
Which is also known as H - zone
Actin is polymerised compound made up of ___ compound
3
Filament of actin is polymer of
Globular unit
Inthe structure of actin two globular unit is attached by using ____
Mg+2
Tropomyosin isa complex protein disturbed at a regular intervals on the tropnin
Tropnin is a complex protein, disturbed at a regular intervals on the tropomyosin
Inthe resting stae tropomyosin masks the active binding site for myosin in the actin filaments
False
Inthis troponin masks the binding site for myosin
Each actin contains ____ tropomyosin
2
Troponin -c received calium from SR
No
From sarcoplasma
Tropnin -I inhibits the
Troponin -t from uplifting the tropomyosin inthe absence of signal( spinal cord and brain)
NM junction has how many components
- Pre synapticembrane = axolemma
- Synpatical clift=gap
- Post synaptic membrane= sacrolemma
Many neuron with a muscle fiber work together and known as motor unit
False
A nurto and many muscles fiber
Neuro transmitter use to transfer signal
Acetyl choline
Sliding of actin over myosin towards _____of ____ band
Center
A band
During shortening of muscles i.e contraction which gets reduced
And which retain the length
I band
A band
Reaction time of muscles does not vary in different muscles
False it vary in different muscles
Slow fiber colour
Red
Because myoglobin are present on large amount
Fast fiber are
PAle or whittish in colour
Red fibers are also called
Slow fiber
Less reaction time is of
Sketal muscles
Fast reaction time of
Heart muscles
More SR and but mitochondria are less in
Fast fibers
Axail bone are and apendicular bone
80
126
Gridle means
The limbs are attached to xail bond
Suture which attached frontal bone to parietal bone
Coronal suture
The temporal bone and parietal bone is attached by
Lateral suture
Lambdoid suture is
Attached parietal bone to occipital bone
The u shaped is persent at the base of
Buccal cavity
The skull region articulate with the vertebral column with the help of
Occipatal condyles
True or false
1. The occipatal bone on the internal or lower side has one opening called mental forame
2. Around mental foramen two occipital condyle ae present hence human skull is diconylur
Both are false it is faramen magnum
What is called trunk
It is the part of body means if we removed head and limbs
Basically neck region
Vertebral column support and protect
Head
Protect spinal cord
Spinal cord function
It serve as the point of attachment for the ribs
It serves as the point of attachment for the musculature of back
Invetebral disc is found at
Mammals
Setrum is flat bone on the dorsally midline of thorax
False ventrally
True or false
1 .Intervertebral disc is made up of elastic cartilage and so called as fibrous cartilage
2. There are 3 process on the lateral side of vertebrae
3.Transerve process provide site for the attachment of back muscles
4. Ribs are attached to 1 site of transerve process
5. Ribs have cartillageat the ventral end for expansion of chest
Wrong are
1.intervertebrate disc is made of collegen cartilage and so called fibrous cartilage
