calming – parasympathetic

25
Q

sympathetic

A

arousing

26
Q

parasympathetic

A

calming

27
Q

Cerebral Meninges

A

Dura Mater,

Arachnoid Membrane,

Pia mater

28
Q

major cerebral arteries

A

Anterior cerebral artery (ACA)

Middle cerebral artery (MCA)

Posterior cerebral artery (PCA)

29
Q

where is CSF produced

A

in ventricals
flows through centeral ventricals and escapes through subachnoid space

it is then absorbed into blood

30
Q

fluid filled caverns inside the brain

A

Ventricular System

31
Q

where is CSF produced

A

in ventricals in a tissue called choroid plexus

32
Q

blas·tu·la

A

an animal embryo at the early stage of development when it is a hollow ball of cells.

33
Q

Embryo beings as a…

A

flat disc

34
Q

three layers of embryos flat disc

A

endoderm

mesoderm

ectoderm

35
Q

first step of nervous system development

A

formation of neural groove.

walss of groove are called neural folds

neural folds come together and form the neural tube

36
Q

what does the PNS develop from

A

neural crest

37
Q

somites

A

mesoderm that give rise to skeletal system and muscles

38
Q

two parts of prepherial nervous system

A

autonomic

somatic

39
Q

autonomic nervous system

A

Acting or occurring involuntarily, without conscious control

40
Q

somatic nervous system

A

The part of the peripheral nervous system that transmits signals from the central nervous system to skeletal muscles, and from receptors of external stimuli, thereby mediating sight, hearing, and touch.

41
Q

where is serotonin produced

A

ralphe nuclei

in hindbrain/brainstem

42
Q

reticular formation

A

contains nuclei involved in neurotransmitter production, nuclei associated with the cranial nerves, descending tracts involved in modulating sensory and motor functions
