Batang utek

Batang utek utawa brainstem (utawa brain stem) iku pérang ngisor saka utek, kang nggandhèngaké lan kanthi struktur nerisaké saluran saraf (spinal cord). Batang utek nyadiakake motor utama lan sensory innervation menyang rai lan gulu liwat saraf kranial (cranial nerves). Sanadyan ukurané mung cilik, batang utek minangka pérangan kang wigati banget minangka pengubung saraf motorik lan saraf sènsor saka pérangan utama utek menyang sakujur awak. Iki kalebu corticospinal tract (motor), posterior column-medial lemniscus pathway (fine touch, sensor getar lan proprioception) lan spinothalamic tract (nyeri, suhu, gatel lan sénggolan /crude touch). Batang utek uga mainaké peran wigati ngenani regulasi fungsi jantung lan sistem ambegan. Batang utek uga ngatur sistem saraf pusat, lan dadi sumbu sajeroning kaanan sadhar lan ngatur siklus turu. Sawetara taksonomi mratélakaké batang utek minangka medulla oblongata (myelencephalon) lan pons (péranganing metencephalon), sawatara liyané kalebu ing midbrain (mesencephalon).
